dual action sander with a really fine grit, 2k or higher, to get the pits out, then use cerium oxide to polish it.
Good video and effort. Sadly, I have the same problem and will end up replacing the windsheild.
Thanks man ya just figured if anyone was in my boat and was planning on trying this stuff just go ahead and skip it
Interesting. Thanks for posting.
Ya man just my experience
So I’ve been able to achieve a visible improvement with the cerium oxide and a DA buffer after going at it for a solid 20 minutes in one spot, but it wasn’t perfect. It would also take at least 2 hours of non-stop buffing to cover the entire windshield, and the putting would only be reduced.
Pro tip here. I assure you that you can remove the pits. But will it be cost affective to do so apposed to just replacing the windscreen? What you have to do is find out roughly how deep the pits are in microns by the way there is 25,400 microns per inch. Then you will have to use a course abrasive pad and water only as lubrication. Run the entire pitted area and the glass will turn very hazy during this phase. never let the glass get above 200*f degrees . like to maintain between 150*-175* by cooling with water in a spray bottle. Then the next step is to a fine abrasive pad and water. Over run the first area by 2 or 3 inches if possible to avoid noticing ridges on the finished glass but in your case you will be doing the entire windscreen anyhow. The heavy hazy will turn a lot lighter with each abrasive step . The next step is to use a very fine abrasive pad with water only in this step the haze will be very fine. Now in the 2nd phase you use the cerium oxide to polish. If mixing the power I like to see it as thick as yogurt. In this phase the glass heats up quickly still maintain the 150*-175*f ish temperature. This phase will turn the glass crystal clear. It would take me several hours and cost around $100.00 for supplies. It's not really worth doing but it can be done!
thank you so much for the info! im going to be trying this on a few of my project cars. buying new glass is not available so i have no other choice! i got some pits on the glass from not being careful enough when grinding, so id like to try and buff them out, at least better than it is. thanks again
I guess if the pitting is deep enough then you would have to remove a lot of glass to polish them out. Also even if the polishing did improve the pitting, if what remained of them has trapped some of the cerium oxide then they would stand out even more so perhaps you need to find a way to clean out the residue trapped in the remaining pits.
Glass is hard to polish and from what I understand, cerium oxide is good for polishing out fine scratches. Anything that you can feel with your fingernail won't come out and even with fine scratches it can take hours of polishing with a rayon pad and a DA to get them out. What you did is probably something that any DIY car guy would do...get some compound and put a polishing pad on their drill. Might be good for removing water spots but that's about it. Thanks for posting this video because it helps to set expectations and I think a lot of people have high expectations based on marketing hype of these products. And wow, what a mess! Glad that your wife made it through the sandstorm with just some etched glass. Sandstorms can be very dangerous at times so I'm happy to hear that she's okay obviously since she made it home and at the end of the day that's all that matters.
Thank you! I appreciate this comment its exactly what I wanted to show the rest of the DIYers out there so they wouldn't expect a miracle from some powder. She made it thru and didn't even stop the car which is what she should have done just pulled over and wait for it to pass . We learned now 😆 🤣 what to do in these situations.
For scratched who you can feel with your finger you'll need sanding paper, when you got out the scratches, THEN you are ready for Cerium Oxide
I saw a glass company use pummace powder first before the cerum oxide
Thanks for the vid. I was looking for proof that it works but im happy to know it doesnt and I wont waste my time.
What others have said about sand paper and heat i dont think Ican botherdd with all that.
Thanks for this video, I have to replace all my windows except the rear in my 2018 Camry, paint and headlights are ruined also. Damn sand.
You could sand the headlights using wet and dry go from 240 grit up to 3000 grit and then polish them, they will come up like new
Same all 4 windows and windshield
in that case, I usually use a sharp razor and a clay bar in order to descontaminate the windshield after polishing with cerium oxide. The success depends on being patient and hard working.
شكراً لك 👍🏽
xyah pki felt pad polish ke?pki span je dh cukup?
Yes, exactly!!!! I have the same!!!!
Bro u gotta tell me is there a way to fix it or is it just time to replace?
Sad to see you didn't succeed, but thanks for showing everyone the reality 😊.
Ya man it was unfortunate thanks for watching
It’s a good experiment though !
Grateful for your video, though. I need to watch my dollars, so thank you!!
Brotha we all do in this economy
Some insurance companies will cover the cost of windshield replacement without a claim or deductible, it can be replaced quickly and easily in your driveway or workplace if there is a chip or crack. I would check into that as well.
Pretty much what we had to do
3m cerium is what you want along with a dual action or at least random orbit polisher (makita or even harbor freights Bauer ) the Bauer 6" is only 100 beans and is actually worth it. You need a speed of 3k with very slow overlapping strokes and decent pressure. Now Griots glass pads work great, but 3m trizact pads are preferred. sand pits at the depth of a grain of sand will not come out. but half depth will and wiper hazing and scratches will vanish. If done right windshield will be less reflective and water will repel better, a result of cerium
Man im digging your comments it reminds me that sometimes research doesn't make up for experience I appreciate it
What type of pad would you recommend for the 3M stuff? I've heard that those glass disks can produce some bad opticals if used improperly. I was able to remove the wiper haze with CeO2 slurry, an orbital & a buffing bonnet turned inside out to the rough fabric side. My orbital crapped out and I tried the same as video w/ same results (or lack thereof). 3" felt wheel -no luck, 6" felt disk skipped all over. I do believe the drill adapter rig is only good for spot removal of scratches.
@David M to be honest my friend you are far ahead of me in these situations I couldn't give sound advice on what works in a particular scenario that's why I tried myself and thsts as far as I got into it.
@davidm3210 yeah that's right, cerium can cause distortion. 100% if used incorrectly
hi
so i bought one of those squeegee wipers from dollarama. terrible mistake. i left some scratch marks on the side passenger windows. but not deep enough for you to feel it on your finger nails. u think this product will fix it up?
thanks
I think this is the perfect application for light scratches
@@weekendwrench thanks
is there a grit number for the applicator that youve used or any that you can recommend? thanks
It's just a cotton pad that comes with it on Amazon ill try to find a link
@@weekendwrench thanksss
I'm late to the party but cerium isn't coarse enough to remove enough glass to make the surface flat. If you started with a heavier grit to flatten the surface and worked your way up to cerium ox,,,more than likely looking through the windshield would be wavy.
yup those ‘stars’ are hard to impossible to remove and worst part is the cerium oxide will clog them up leaving an uglier visual mess … i know coz ive done it … it was a mess of an attempt … so ive left with two choices … replace the windshield or live with it … i chose the latter … have a nice day bro.
boom
😎
You would have removed the pits eventually. it would just have taken a LONNGG TIME. I'm talking hours of polishing a single area. You should have started with a more aggressive glass cutting compound and then finish off with the cerium oxide polishing compound once you got rid of the pits.
Oh and it's a good idea to cover the paint around the windshield since you're working with an abrasive.
Mine is similiar. Not as bad but maybe 50% there. I think mine is due to ice, since i bought my car from canada.
What did you end up doing?
Replaced the windshield brotha it makes no sense to spend 8 to 15 hours and possibly not make any progress when a windshield replacement is about $200 with guaranteed results
ice wont chip glass, its just rock/sand hits at speed on the highway.
and its not THAT cold up here!
Used cerum oxide got the big scratch barely visible but got lots of swirl marks even after polishing with autoglym glass polish any ideas what steps to do next?
Replace the windshield
What grit abrasive pad did you use?
@@stackmosayless-1669 not 100% sure it was the yellow followed by the red cerum oxide and autoglym glass polish afterwards
@weekendwrench window would cost more than the car is worth, besides they are micro swirls just need to figure out tye next step to get those less visible
@@A7Xdookie my man if u figure it out come back here and let us know what u did and what u used
Seems to me a round with more course grit would help. You'd scratch the hell out of it with the course and polish it out with increasingly fine grit. I don't see how it could hurt to try.
Could wind up with a messed up windshield. Glass is extremely hard & we are trying to achieve a very high level of polish.
It's only for optical micro scratch, not for nail scratch.
You have to use corded drill bro + don’t make it dry just keeping put some water
Why does it have to be corded?
That cerium oxide is only good for removing calcium deposits. For that windshield first you need to sand it with different diamond pads( from ~500 to 1000-1500) and after that the polish
I think a call to your insurance company to have the windshield replaced would have been cheaper and less time consuming. Interesting experiment though.
For a 500 dollar deductible vs the 24 dollars I spent on product and my own time is my own free time is not worth it and a new windshield was only 230 dollars by itself still not worth the deductible.
use 2500 + grit sandpaper
First off you should have used a corded drill, and an actual rayon glass polishing pad. Your results would have been significantly better
Love the enthusiasm but I politely disagree, after talking to actual glazers there is no actual fix to pitting in windows unless u have a flat panel of glass which we know a windshield is not flat unless u have a jeep.....maybe, then u need special equipment to resurface it. This will not do that.
@weekendwrench that is true what u are using will not remove pitting and depending on the depth of the pits you would more than likely end up distorting the windshield trying to remove them. For light scratches and shallow pits, they have glass sanding discs made specifically for this type of work and you follow that up with rayon glass polishing pads or lake country polishing pads with ceriglass or cerium oxide, I've even used hand soap containing hummus and mixed in rubbing compound which works really really well for wiper scratches. My original comment wasn't meant to lead you to think your results would have been a perfect windshield but u would have stood a better chance at getting the shallow pits out after several hours of serious grinding it out. I'm not a professional just sharing my experiences and limited knowledge
you can not correct deep pitting. think your polisher can only correct what it can make contact with... Also that crap you were using is subpar. good cerium oxide is a bit pricey and really works quite well. unfortunately deep pitting is there forever
Pro Tip from professional detailer. Use a felt pad, you are using a foam pad, that is too soft of a pad for anything. Also the pits might be too deep to be polished out anyway. Might just be better off using comprehensive insurance to replace the glass
cerium oxide is very fine polishing. Pitting is too deep. You need to take sandpaper to that stuff before bothering with cerium oxide.
Looks like you're using a foam pad which is a huge mistake if you are. You need a glass polishing pad which has little to no foam backing. Also, you're using too much water which is heavily diluting/ washing away the paste (which looks to be too thick in the first place). Polish 1/4 of the windshield for about 20-30 minutes straight or even longer with heavy downward pressure to achieve results.
It's the glass polishing pad that came with the cerium oxide
I spent over 1.5 hours with different textures, it can't be too thick and too much water at the same time. Overall I firmly believe cerium oxide helped with scratches and imperfections but not for pits
No, no. They make foam pads that can be used for heavy cutting to no cutting to anything in-between. He is using to much material. He also needs to work a small area, clean, and then continue working the area until the desired result. The drill isn't sufficient in this case also which is probably a moot point anyhow. I managed a detail business for 14 years and buffed tens of thousands of vehicles, btw. Glass is an entirely different beast though and replacement is typically the only true option.
@@weekendwrench Yes, that was the correct felt pad. I'm just a diy'er but I think your effort was sound, just that the pitting was too severe.
'
@@davidm3210 exactly 💯
But those are chips, I don’t think it is supposed to remove anything that aggressive… i bought it for very aggressive watermarks. I hope it will work. If anyone is interested leave a comment in like a month or so because I don’t know how soon I’ll actually do it…
Thanks for showing a negative result! The pits are much deeper than wiper scratches and it seems that there is nothing on the market that gets deep enough.
Ya man no problem thanks for the comment I know there's a lot of pros out there this was just my experience with it
Tried it. Didn't work
Lol can confirm 🤣 what we're u working on?
That's low quality cerium. But even if it was pure, it wouldn't be able to fix the problem in the video. It can also make one hell of a mess if you don't contain the product and mask the car.
Brother you are correct on all accords and it absolutely made a terrible mess.
Aluminium oxide cuts harder I think
Maybe so but this type of work particularly glass is well out of my realm
Wrong lol
Sound quality is really crap
Yeah, next time he should use a Hollywood sound stage.
(It's a DIY video)
You need to Sand It down first
How would I sand glass down? It would turn the glass into just scratches
I heard clay bars do the trick.
I mean I don't see how clay bar will eliminate the pits if an actual glass abrasive didn't work tho
So I’ve been able to achieve a visible improvement with the cerium oxide and a DA buffer after going at it for a solid 20 minutes in one spot, but it wasn’t perfect. It would also take at least 2 hours of non-stop buffing to cover the entire windshield, and the putting would only be reduced.
