I've used 303 once 2 1/2 years ago and it still looks great
Great stuff! I use it on my spa cover and on the rubber roof of my trailer
If you park your car outside permanently here in Australia you're going to have issues if you don't apply a protectant, maybe not 12 times a year but at least 4 or 5 perhaps. The sun here can be brutal.
I've just used Armoral matte finish for years. My interior looks like new even baking in the Perth summers and now I'm in Brisbane. I apply it about 6 times a year.
@@OFFICIAL_VIDEO_AWARDS Good on you. I have not used any Armor-All anything since forever ago, when their original spray that they sold as a "protectant" that simply dried out dash plastic and make any cracking worse.
What do you consider brutal in Australia? I'm from AZ where temps are 110F to 120F in the Summer. It's also very dry which makes the plastics very brittle. AZ is great against rust but very harsh against plastic. I just moved to the Southeast where its not as hot in the summer but very humid, 85F to 100F degrees with up to 100% humidity, so rust is a bigger problem.
Great video Scott. I have gotten by using meguiars quik interior cleaner. And I just started on griots interior cleaner. I have never used a dressing per se on the interior trim. I did like the fact that there are water based products out there and like on a recent video of yours using diluted vrp to achieve a desired effect.
Your honesty is what keeps me engaged. Keep up the good work
I have to agree with Scott. Out of ignorance, I did nothing to my 2005 Honda for four years. Both my paint and interior cloth was sun bleached, I had some clear coat damage, some rubber molding broke down and the glue on the interior headliner and door panels failed. But the plastic interior dash and plastic door trim held up remarkably well. No cracking, no fading. There is no need to use UV protection very often on modern cars anymore.
The most realistic review. Thanks
I am new to 303 and have used it on my two cars now only one time at the current car clean. A 2003 mazda 6 and a 2006 grand marquis. I only ever used Armor All before. I do like that 303 gave my plastics a deep rich color and there is just a hint of shine until it completely soaks in. But frequent application will keep that deep rich color, a healthy look to the inside of my car. If I remember Trim Shine when my bottle is empty I will get a bottle and try that.
I spray this stuff generously in the engine bay after washing it. It makes everything shine and as added bonus, it prevents future dirt from from sticking to plastics, rubbers, hoses, etc which makes the next wash easier
I use 303 it's great stuff.
I agree Scott, think maybe I shine my own personal cars 2 times a year using chemical guys silk shine and it looks good all year. Thanks for the heads up was wondering about 303.
Here in the Nevada desert I use it at the start of our summer heat and at the end so July and then October. That’s for the interior rubber seals dash and any vinyl. Same outside including the headlight and tail light lenses. That’s in my 2010 fj cruiser. It doesn’t shine but it does clean and I think protects really well. A crazy friend of mine applies sunscreen lotion with SPF 100. Banana boat and nutragena brand. His car is never garaged and it seems to work. Won’t hurt your skin so it should be okay on vinyl, plastic and rubber. He applies it once a month. The banana boat he uses for the interior so it leaves a nice scent that the women like 😎
You got me, I clean and wax seasonally and to be honest it works well but I also keep my vehicle in the garage.
I apply this about three times a year to our three cars,but then I live in the UK so not that hot in summertime however I do use it on my LR discovery D4 that we drive to Spain and in my opinion it definitely helps keeping the dash looking fine and protected in the hot Spanish sunshine.I thoroughly recommend 303.
Wow I’m doing it wrong lol I do 303 cleaner then 303 protectant about every 2 weeks on interior
But I do have a mini weenier dog who sheds alottt
I just want to say thank you for doing this your videos have really helped me and u do sound like ray ramono
I bought one gallon of 303 when I bought a new vehicle, economy of scale/ I’ve used it on average 8 times a year exterior and interior. I feel like it’s made a difference, I live in sunny so cal.
its great for exterior plastic trims. It helps restore their color from faded black with white residue to full black.
I bought 303 gallon size for about $40 and I do apply once a month give and take. I keep the product in my car.
Excellent, thank you buddy. Great job.
303 has an SPF of 40. My original white bottle has that information.
very cool..thank you for the info
@@dallaspaintcorrectionautod8343 Yes the origila aerospace bottle it sais 40 spf BUT in the newer aytomitive bottle version surprizly the spf rate is NO mentioned in the label at ALL..............it is very suspicious......
And if we consider that the front windshield has constantly 60 spf and the side windowes 15-30 spf rate constantly.............and we never know how much the 303 can hold the 40 spf rate after the application.....then the Scott video it is making a lot more sence that.............DO NOT OVER THINK IT
I think the ORIGINAL white bottle is all you really need...
@A OK i prefer with coconut scent!!!!!!
@@mercedesbenzs600bash what does the original smell like?
Great call, great vid.
- thanx
I think this depends a lot on where you live and if your car is garage kept or out in the sun all day. South Florida, definitely need some sun protection, especially on leather seats and the headlights, if you don't have a garage!
Excellent points !!!
just a guess perhaps 303 application interval is to help stop complaints from people who own 80's vintage cars with plastic interiors that are looking for a like new appearance that would last more than a month.
I know if 303 were available in the 80's I would have used it on my rx7. I know the armorall that I used once was to greasy and seem to promote interior cracking. I ended up not using any protectant
I'm going to start using it on my Z32 before I have any interior parts crack
Thank you for saying the truth.
On point as usual.
303 is great stuff. I dress the engine bay with it. $40 a gallon on amazon. I think it looks great and I feel like it protects the belts and hoses reasonably well. Guess I'm just a fan boy :)
I re apply after 3 hours at the beach, keeps your skin soft too.
Works good on condoms, too.
I use simple green wipes in the canister - doesn't hurt anything, picks up the dust, and I use sun shades in the windows - my car is a 2008 and it's just fine.
I think 🤔 u sound like Ray Romano
SteelTxGal Thanks, now all I can see is Ray Romano when I watch this channel.
I felt i was listening to the Storage Wars guy
You are actually correct :) .
Fricken 10th person that said that get over it
I use and have been using Meguiars Quick Interior Detailer and have never had interiors fade. If a customers wants a "dressed" look I reach for CarPro Perl (heavily diluted), or Meguiars Hyper Dressing (heavily diluted).
I've used and tried all sorts of protectants starting with Armor All way back (that stuff is crap compared to what is available now). I really like the way the 303 goes on. The only one I have liked as much is Mr. Wizards but that stuff is even more and hard to find. I do get Formula 1 protectant through work dirt cheap. I use it first on really faded parts or budget detail jobs. It reminds me of old Armor All though.
I will but I’m an enthusiast. My car has to be clean and perfect or I get anxiety.
I love this stuff. Goes on smooth and looks nice. Works on tires too.
You did not use the 303 correctly. Read the directions. You spemd more time buffing it off then you do applying it. When done correctly.
303 isn't the only product out there to say "protection for weeks" there are many that claim that. But how many tell you how many weeks for maximum protection? I personally treat my interior every time it starts getting overly dusty, which means it varies from 1-3 months depending on how much I'm opening my windows. I love 303, especially on my tires, really keeps the dust and grime off while keeping a nice satin finish. Want to know how a product does keeping dirt off, spray both of these products on your tires and drive a mile or two through a dirt road, see which one keeps the tires cleaner.
I use it every week!
it
Automobile plastics, rubber and the like are light years beyond what they were even in the 90’s. Most automobile companies test their plastic and paint formulations in the Arizona desert 🌵, yes there’s a actual testing facility where that’s all they do. So extreme advances in formulations have been made. That said, I still think 303 is worth the investment for a car you plan to keep for the long run. It’s proven to protect plastics and rubber. The effect it has on rubber specifically is very impressive! I use it on my host primarily and the vinyl looks new (it’s a 1987 ski boat).
I have a 2000 outback. What do you use to clean your interior plastic and vinyl. I have used baby wipes alcohol free wipes. They just leave fibers behind. Love your vids by the way.
I use i 3/4 times a year and i seems o do a good job I'm happy
do you do it for uv protection or do you like how it looks?...I guess 303 recommends to apply once a month for uv protection
303 also states that it protects for up to 6 months. Sure if you want the absolute best protection then you have to apply it 10-12 times a year but for an automobile, you don’t really need that. If you’ve got a boat or a convertible where the interior is in direct sunlight and doesn’t have automotive glass taking some of the “sting” out of the sunlight, you do really need to apply it that often. For all other cars, once a season is perfect. If you’re in a really hot climate then throw in an extra top off application in the middle of the summer months when the sun’s rays are strongest. If you’ve got a proper winter/fall season... then you can get away with one application for both since there’s no danger of uv rays in the winter and barely any in the fall.
Great video and your correct the 303 cost me around 15 dollars in autozone and was told this would be good for the tongue cover and i see that you were demonstrating on doing the door panel do you think this can be used on the tongue cover too ?? If so im definitely doing something wrong !! If you have any ideas i would appreciate your input, the cover is in good shape but it needs some love and i was hoping to make it pop ! Like i said autozone told me it would work!! I appreciate your video just like to know what you think!! Thanks and i appreciate it!!!!!
Scott, do mind me asking what you use in and out your personal cars?
The Formula 303 company just wants you to buy more of their product!
I would believe that some protectant is better than none. In todays age with todays plastic, being made cheaply "Not better" I would rather Have some protectant than none at all.,
I have two Infiniti's home. One is 2003 FX45, last year i found two cracks on the dash, now i am upto 4, Not very Notocable. But enough that it bothers me. Also I am from NY like you Scott 😁 You know it not hot all year long down hear and the sun isn't as intense here in Queens, but my dash has cracks on it. Lot's of Modern Cars have Dash issues, bubbling, peeling, cracking, spliting etc. I think that is all do to cheaper quality material used in order to Maximize their Profits.
Also, I have noticed a difference, in feel and look of my dash using 303 Protectant , So for me, I am very Satisfied with the Product and i think it's Superior to other brands, because of the look and feel of my treated dash.
I think at $14-16+ for a 16oz Bottle is a bit over priced. I picked up three bottles of 303 Protectant, on amazon $6.16 as an "Add On Item". So i took advantage 😁
Thank You from a New Subscriber !
This was a great video. Thanks for the insight. I agree with you that both products are pretty much the same and deliver the same benefits. I bet if you did an experiment and used the 303 twelve times a year and the Stoners Trim Shine a few times a year, you'd most likely get the same results.
So I use various UV type products once a month. Maybe once every 2 months. Adam's VRT, Leather Conditioner, etc. In between I use their Interior Detailer. Am I just removing the protectant with the detailer? I like the matte finish and you have to use something to get the dust off. I spray the microfiber and lightly swipe because it's a weekender car and doesn't get dirty, just dusty from driving
In one video you recommended Protectall....do you prefer that over other products for the interior? Various recommendations are scattered across a bunch of videos and can be a bit confusing. It would nice if you could do a video with your top current products that you recommend for certain tasks.
With me first time using it the 303 soaked in and it was gone did 3 applications and after it dried rubbed it and it had little shine and does huge on tires here it’s $16 a bottle used to get gallon at parts store I’m going online to order it’s way cheaper
whats the difference between a dressing like meguires hyper dressing or cg vrp vs a protectant like this one or similar ones?
It depends where you keep your car outside so it does come to play from dust,sweat / environment
I originally used 303 40 years ago on scuba equipment. It most defiinitely protected rubber from UV degredation. Most of that equipment still in usable condition today.
I don't know if applying it to modern car interiors is beneficial or necessary. I used it in a 2004 Element for 11 years, treating the extensive plastic cladding and fenders and the tire sidewalls. They had scratching but otherwise looked like new when I replaced that car in 2015. I removed exterior trim pieces the first year to install a roof rack and stored them in my home. When reinstalled 10 years later, those pieces perfectly matched the surrounding plastic.
Regarding cost: 303's original directions were to apply, and after 24 houts, wipe away any excess. The claim was that it bonded with the plastic. My guessis that with few people able to not use a cars for 24 hours after applications, the application interval was reduced to reflect less material being left on the surface.
I never waited for 24 hours for an interior application to "cure" but I never polished it away as shown in this video. One 16 oz bottle applied to all the exterior plastc and rubber, all the CLEANED interior hard plastic, was enough to do the entire SUV 24 times. My trick was to use the smallest possible piece of cloth that I could manipulate and apply a few drops of 303 to it whenever it was no longer leaving a visible coating. The only chemical I've ever used for a car surface protectant than came close to that level of coverage was Meguiars Paint Protect.
My theory is that the reason the exterior plastic looked like new was that it wasn't coated with layers of degraded waxes and embedded grime, because I was scrupuous about keeping wax off the plastic. I believe the interior plastic didn't need a protectant, becasue a used Element I bought with 8 years heavy use that has no sign of ever being detailled before I bought it has like new interior plastic everywhere except where the woman onwer rested her over-lubricated left arm on the door. After cleaning that panel with APC and LVP cleaner, it looked as good as new.
pssst3 303 hasn't been around for 40 years lol
@@kenlawton1531 supposedly it's been around since 1980
Once a year or maybe for extreme cases twice a year is what I see as a professional detailer. Most of my clients do an interior detailing in the spring, so that is once a year.
Excellent love you
What do you clean your interior with before applying these products?
Can you do something on Toyota sof-tex ,synthetic leather?
I agree to a point - I think that over a period of many, many years in pretty harsh conditions (say in Nevada or Arizona) the plastics (even modern ones, especially since they're "greener" now) may be about as bad off as those we saw in the late 80's through the mid 90's. I really do think (and again agree) that one can go overboard by following the directions in a strict fashion - my guess is that using 303 once a month won't "hurt anything" but it probably won't help that much more vs. a couple times a year. Some other TH-camrs swear by 303 Aerospace - I think they add it to their coffee in the morning (not really but they seem to use it on everything else) - I think you said something that was "key" - people overthink stuff and the reality is that people really don't keep cars all that long and the vast majority of cars that over 10 years old today will never be "classics" or worth any more later than they are worth today.
To really see the difference that 303 makes, you really need to be in the marine application, where heavy UV exposure all day every day is a constant thing. In the automotive world, maybe if someone parks outside in a desert climate. The product's distinguishing characteristic is that the UV protection is LEGIT.. but if you want the highest level of sun protection, you do have to reapply monthly. Protection from dust/dirt is secondary and not unique. ALSO it is indeed water soluble and will wash off at the slightest contact with water, a minus. But it is the real business in its niche, and highly suitable for automotive interiors.
My car detailer swears by 303, because it does not give you a linting problem. I have been using it about a year. I put it on 3 and 4 times a year, no lint problem. With all the pl
Glossier products attracted lint
I've used 303 since it first appeared, like 20 years ago. First, I don't believe SPF is a valid measure for other than human skin exposure, and while upholstery may be like skin it is not necessarily prone to the same type of damage; windscreens may have SPF 60, but that is to protect the occupants. 303 at least in Colorado altitudes does not last very long on exterior surfaces; I've been using Outlast with better results, but ICE wax lasts at least 6 months so that's my exterior choice. 303 leaves no apparent change, greasiness, color or texture change on either plastic or leather, not slippery beyond an easier surface to dust. It also does NOT do the interior windshield condensation that silicone oils produce, an obvious sign that they are really just coatings that vaporize when hot, leaving no protection beyond a simple oil coating. So far nothing ever seems to reverse aging in vinyl, a disappointment in a 2012 white Impreza; perhaps sweat and not UV is the culprit?
I use this for my viper blades and I never have to replace them it keeps the rubber conditioned
I'm pretty sure 303 is owned by a windshield wiper manufacturer.. lol so you're probably using it for what they use it for.
How do you apply it to viper blades?
@@gittyupalice96 wiper blades? wouldnt that streak over the glass
@@randomrazr u have to let it soak in
@@randomrazr Its used to condition the rubber, otherwise it would dry-rot and crack apart in less than a year. I understand that manufacturers use various coatings on the rubber blades.. I cant 100% confirm that 303 is used for this... BUT its suspicious to me that a company who makes wipers also owns 303 lol. just putting 2 and 2 together.
Visual looks vs. what the components of the two sprays have in them are completely different. You may get the same look but are you getting the same protection? One person said 303 is rated for SPF 40. If that is true is the other spray comparable? One thing I have yet to see is anyone taking like a car dash and putting it out in the sun for a year or two, making a video showing a raw dash, a protected dash and what the difference would be after a year or so. That would be interesting.
I do use it couple of weeks but I'm crazy.
gil zur me too !
My former bubblegum Camry dashboard really made me think hard about UV protectant. I bet replacing all those dashboards made Toyota think really hard about investing in better materials. I swear my parents had some type of leather in their Camry as the dashboard material.
What do you clean this nissan rubbery fealing dash with? Seems like everything wants to stick to it
Scott, I appreciate and enjoy your videos. Workz owes you some royalty....I purchased the portable power washer after watching your videos. It is great!
On to 303, I live in FL and use it on almost every surface possible (car, boats, etc) I use it about every 3 months and it seems to work just fine. I would love t see a long term test of the protect to actually prove how much SPF it really has,, but until then, 303 has me convinced to use it! Plus I like the way it looks. Keep up the great videos!
i have that 303. one thing i notice is if like opening the door on a rainy day and the door panel with 303 gets wet and i was not able to wipe it and gets dried out the next day, there is a "rundown" mark or streaks. i dont know if anybody experienced it or its just me. very nice vid scott, helped me bought alot of products because of your real-world reviews
grey fort read the directions you need to spend time after you apply it to buff it off.
It has on the directions that it does not air dry. So, if you apply too much or do not follow the application of wiping with another clean dry microfiber, you will get the streaking effect.
is it worth using all thee protectants for a new car?
I Like the Wet Look it Leaves and stays there for at least 4-5 weeks, but i don't know if it is really non toxic. It does not evaporate away so must have some sort of oil in it, i'm thinking coconut. Really does make interior look new and nice. I was told bowdens was great but does not look like you even applied anything its just dry compared to 303.
Sweet everybody loves Raymond !
I didn't know Ray Romano ran an auto detailing company.
i was wondering how well it works in a engine bay detail?
Mother's M-Tech protectant also protects up to 30 days
Nice video
How do I know if a plastic protectant or tire shine is water based?
Since its the SUMMER SUN, that has the STRONGEST UV rays, id go ahead and use it may june july august. The rest of the year every 3 months. The California desert sun is super strong, and today the temp reached 117 f !
The difference is that 303 can be applied on most surfaces such as leather. Can the trim shine do that?
yes trim shine is water based just like 303 so its safe on leather...we also need to remember that most modern day leather is coated in a form of plastic, so just about anything can be applied to leather:)
I use it weekly. Every week I clean inside and out. Vehicles are washed weekly.
Any long term update? I have cars with leather interiors and plastic and I'm super anal about the products I use and don't want things cracking.
Do you have a step by step video talking about general steps cleaning a leather interior and protecting it or maintain it. I got a 06 acura tl stick. leather interior. I wanna clean it protect it and keep it maintained i hate dirty interiors. Its my first leather car. What do you recommend products wise?
I hate the frying/worn leather steerings/shift knobs/armrest. Mine are in really good condition and i would like to keep it that way. Something worth the money. See a lot of products at stores which confuse u dont know what works what doesnt. Im not a detailer or anything so i dont need anything crazy.
Btw I like matte look or clean even minimal shine(dont like the wet look). Keep up the good work!
5Riverz if you have the time and money, get leatherique, it's expensive but it will make you leather look brand new. The dirt just melts off
I have an 04 Mercury Grand Marquis LS and like you it is my first leather car. It's in above average conditions except the drivers seat which is about average. It has 213,000 miles because it was a rental car. I personally clean it with a diluted interior apc cleaner or a dedicated leather cleaner. The conditioner I use Lexol Deep leather conditioner and it works wonders you can get it at Walmart. I'll clean then condition. For the drivers seat I'll spray some on the seat rub it around with my hand let it sit for 5 minutes then wipe off. The rest of the car I just use an applicator pad. I've never had any issues I do it about once a month and it leaves a nice smell in the car for 2 days after
I believe and this is just my opinion but if you keep your plastic vinyl clean free of dust build up that there is 3/4 the battle with occasional application of dressing.
good stuff.🤔👍
Whats the difference between blue bottle 303 vs white bottle aerospace 303....i love sun of a gun but thats discontinued armorall but is slippery
I've been thinking about buying 303 but maybe not so much now. It seems to be a little more pricier here.
I seen people use at 303 on fan belts and things like that and claim they last 300,000 miles. I wonder is Stoners trimming dressing would do the same?
What would happen if you put the 303 on the car? I only had a partial bra on my car for a week and it rained but I also put the 303 on the bra and when I took it off it left this muddled cloudy mess but it has since evaporated. But I still can see it. Omg help!!!
Anybody who owns a boat especially one used in Salt water knows nothing protects and lasts as long as 303. That is where 303 earned its well deserved reputation. The ocean is one of the harshest environments on earth and few products stand up to its test 303 does which is why people like me figured if it keeps my boat vinyl looking great then my truck would really benefit. Here in the harsh northeast I use 303 twice a year to protect my tourno cover and my dash. I use stoner trim shine my doors and engine mainly because it's so easy to apply and holds up great in area not constantly in direct sunlight. If you want to truly compare do something plastic that sits outside in the sun & weather and see for yourself which lasts. PS nothing cleans dirty marine vinyl like Megs HD vinyl cleaner.
yes i understand...but also 303 says you need to use it every 3-5 weeks...thats 12 times a year!..perhaps vinyl and interior plastics are strong enough so that we only need to really use it a few times a year and we will be fine:)
Dallas Paint Correction & Auto Detailing c no idea why they would say that except maybe in the marine environment where a boat sits in the unobstructed sun plus reflection off the water plus salt water. As I said, that's 303s traditional market. It's the only thing some marine stores even bother carrying. On an automobile 1x or 2x a year is all that's needed. I do my torneau cover 2x a year in fall and spring and it still looks brand new after 5 years here in New England. I never tried it on the external hard black trim but will shortly as a test.
303 does not last all that long in all honesty. That said, I love the product and use it on my personal and client's cars and boats. It looks fantastic on vinyls and plastics. I buy it by the gallon.
so the 303 marine aerospace is different than this? i wonder if its the same shit just less expensive.
The Trim Shine bottle says "Lasts for Weeks" right on the front label. Is that any different than the fine print on back of 303 label?
They can and will say anything on a label..lol
Its so objective
Use any non greasy oil like essential oils and wipe the excess off.
you don't put sun screen on one a year if your out in the sun, maybe it's for the uv protection
Not exactly sure, but I think the parent company of 303 is TRICO wich is a windshield wiper manufacturer.. I'm assuming they needed something to keep rubber wiper blades from breaking down, and so they purchased either the patent or the company producing 303... I can't tell because the information isn't readily available to me. MY POINT IS lol, they probably are saying apply it 12 times a year to garuntee that plastics/rubbers will be UV protected in the worse case scenario... Like in a desert climate. I don't think this applys to the rest of the world where there is trees and cloudy days/parking garages and so on.. So it should be acceptable to do it once every 2 or 3 months in my opinion thats not over-doing it and should keep the plastics safe.
I like to put protectant on every 3 months
I have two problems with all the protectants. Don't they offgas in the heat and sun and then you open up your car, get in and breathe all these fumes? Also doesn't it make the interior windows greasy super hard to clean the smeary film left behind? And I just bought the products you previously recommended for washing and sealing leather seats???? (fast finish, Woolite, etc) and was about to do my 2017 Jeep leather seats.
303 is water based and bonds to the surface when applied correctly. Others are petroleum based which builds up on glass during evap. Not with 303.
Windshield glass has plastic in the middle, which blocks 100% of the UV, and side windows have UV-blocking chemicals added that, varying by manufacturer block, I believe like 95%. So why, on modern cars, do we need a UV-blocker on the interior?
You guys have interiors?
I gotta say....lotions for your skin...you can use 10 different lotions and once it dries they all can look the same but what they DO for you can be completely different. There's a reason that for umpteenth years pilots and exotic car owners have been using 303 and not stoners trim shine and im willing to bet it has to do with a highly researched formula. No....I don't use 303 twelve times a year because I don't feel the necessity but I do use it 3 to 4 times per year amd you don't have to use much at all each time. I've found with other "plastic lubes" people really have heavy hands when applying. 303 is different and they even say DONT APPLY TOO MUCH or you need to wipe it off. Yes, it's 15 bucks a bottle vs 6 but if you're only buying 1 bottle a year isn't she worth it????
My common sense opinion. Based on personal experience, it all depends on where you live. While living in Texas, I seen cracks on interior vehicle parts. The heat is so strong that it feels like an oven. Some cities in California, definitely in Arizona, Nevada, Utah, New Mexico are the same. My experience in Western Washington State much different. I see many older vehicles with original paint looking good. There interior are excellent. The weather is much more cooler. 303 in my opinion is a much better product. I’ve noticed on hot days that the other products tend to aerosolize onto your windshield. Cleaning this involved multiple towels. I used to get a film on my windshield only noticeable at night. Armor All is a bad product for vehicle interiors. As far as how much( many) times. It is less in northern cooler states.
I assume that 303 is giving advice that meets the worst case scenario. If your car is outside in the Phoenix sun, then use protection once a month. If you live somewhere that gets much less sun or you park in a garage or you cover the car, then you don’t need as much protection but you’ll have to guess how much you need. If you use less and guess wrong, then 303 will say that’s on you.
How do you clean your car interior before applying 303 protectant?
