Does CRC Zinc-It Work?

- What is CRC Zinc-It?
Is it just primer?
Why isn't it shiny?
Ok, so I'm late to the world of CRC's zinc products. But! When I did get around to using it, it wasn't what I was expecting.
CRC claims this to be 93% pure zinc that actively fights rust. Will it do the job?
The key to cold galvanizing is heating the material to chase out all the moisture and spray it on warm base metal. Then warm it while wet. It’s used on cut ends of steel on critical infrastructures. It’s not as good as electrolysis or hot dipping of course.
Looks like it worked just fine in this video...
But It works great.
The problem with this test is since both paints are on the same piece of metal the zinc coating will prevent rust from forming under the primer. That's why the zinc is already discolored, it's already been sacrificing it's self. Looks like a great product though, I'd like to see this stuff on the frames of vehicles in the rust belt, rather than coatings which just try to seal the frame from contact with salt and water which never works.
If you want a "shiny" look then you have to use a cold galvanizing product that has a lower zinc content, around 65%. This product probably has a bout 90 to 93% so it will be a dull finish. I do agree that the cap color is misleading, as for the pictures on the can well they're stating what you can use it on not what it will look like.
You can paint over it as well.
Check "10 year of using cold galvanizing compound". I switched to cosmoline and fluid film. CGC I use still always at exhaust and work excellent. My pickup is 23 year old and has original exhaust. Especially check my test in #28 who may interest.
I checked, I don't see any pictures and from the comments idk what the results are. I'm curious what actually happened because if applied properly, galvanizing is way better than any crappy coating.
@@bobbygetsbanned6049 Hot dip galvanizing is way better than anything. But this is only zinc rich paint. Have not much to do with HDG.
@@bobbygetsbanned6049 I do not know why you do not see pictures.
@@zell863 They are working now, weird. I wonder how much wasn't sprayed on bare metal because there's no reason it shouldn't work.
I've used the Rustoleum product with great results for many years. Seems to go on about the same as the CRC product.
Another good informative video. A few weeks ago you offered Zinc-it as a possibility as a covering for my window regulators but I don't think you had any experience with it at that time. I haven't had the opportunity to try it out yet so I'm especially glad to see you demonstration. I think it should be okay for my regulators -- it's unseen & protects the metal. Who could ask for anything more? I remember reading a review on the Zinc-it where the person said that there are more steps than just spraying it on. It appears you nipped that review in the bud. Thanks for the info!
Imagine CGC spray, acid etch primer, Automotive enamel paint primer, then topcoat paint, and then clear coat 😂
Acid etch primer first then CGC, etc
I have not used a cold galvanizing product before, but I'm going to give this a shot today as a primer over some bare areas on an ornamental iron railing that our shop built and had hot dipped galvanized. There were some areas where the galvanizing company did a poor job, and I had to file them down because they galvanized over rust and dirt, so those areas are bare steel now and need to be recoated. Before spraying the CRC, I will first use a product called Galvaprep, which I have used for years, it will etch the bare metal spots as well as condition the remaining hot dipped galvanizing for the CRC. Then, after touching up with CRC, I will be spraying the entire railing with Rustoleum flat black, using my HVLP spray gun. This railing will be installed outdoors in our coastal town, so my results will get a thorough testing. Thanks for the video. By the way, CRC stands for Chemcal Rubber Company, and they have for many decades published the CRC Hndbook of Chemistry and Physics, long familiar with the scientific and engineering communities. Look it up!
Thanks for a great review! I can think of a few things I can use that product for. I’d be interested to see how it does after about 6 months
I'm curious to know how the storm trooper helmet turned out.
I bought two yard wind ornaments from an artisan and sadly they began to rust really badly, so I just found your video and I think the solution that is right for me. I will of course remove the rust first. Being able to spray rather than electro coat is way easier. I really like the mottled finish after a month. I would be very interested to see how it does over time. 6 months, yr, two yrs. Thank you!
It will be 6 months in a few days and there will be an update video coming. I don't think you will be disappointed.
Good ventilation is a must.
Definitely interested in a update on this project!
Let’s see how it’s holding up !
Nice review You should revisit it once a month while leaving it outside until you see the first rust spot. Thanks
Yep revisit at your discretion.
Would be nice if you made múltiples and shipped all corners and all weathers of the USA. Your weather is different than the harsher south east coast.
Follow up
I'd take the test specimen to the ocean and throw it in.
Good excuse to go to Disneyland.
Hey Jay. Good video. Yea, it's hard to find something that works the way they advertise. Thanks for sharing.🍁👍👍
Prime and paint can get us the shiny result it seems for the same price
Would love a follow-up I'm building a flat deck for my pickup truck and I'm thinking about using this product on the bottom before painting.
6 month follow-up here: th-cam.com/video/G7cf8wIUsas/w-d-xo.html
will do 1 year update in 2 weeks!
@@TheJayhawker Been a year, brother.
Where is the video???
Hi there! How is it holding up?
Nice video!
I see it's been uploaded 6 months ago, so I would be interested to see how it looks now.

Do you think I should use zinc or that other primer on my wheel arches??
I would prefer to use primer on body panels
Can you paint on top of it?
From CRC's data sheet: CRC Zinc It can act as a finish coat on clean iron, steel and their welds. Top-coating CRC Zinc
It with another product of CRC’s Zinc coating range provides extra protection and a selection of
bright metallic or coloured gloss finishes - the ultimate choice for your application. If other
colours are required, CRC Zinc It can be top-coated with most standard decorative paint
systems for metals
hmmmm likes like useful patina as well.
Hi, is suitable for cars and areas that are prone to rust?
Sorry, I couldn't give you a good opinion on areas that are subject to sand, gravel, water etc. being sprayed at them by the tires. Maybe that should be the next test...
I'd like to see this on some car frames. There's no reason it shouldn't work.
@@TheJayhawker I'd love to see that test. The benefit to galvanizing is it protects the metal without perfect coverage. It's not like coatings where if you miss a spot rust will develop in that spot, get under the coating, then you're screwed. If this cold "galvanizing" actually works, it should corrode the zinc coating first before the base metal, even if the base metal isn't 100% covered.
So is it necessary to paint on it after or is it possible just to use it "as is"?
either way
Looks great. Much easier, faster and probably cheaper than sending out for hot dipped.
