ZRC 10000 Cold Galvanizing Compound | 12 Ounce Aerosol Can | Iron and Steel Corrosion Protection | Matches Hot-Dip Galvanized Performance | Contains 95-Percent Metallic Zinc

This product is great. One thing to note, I am doing antenna sections that are 10 feet long. I bought two cans thinking that would be ample for a 45 foot antenna. In actuality one can goes about 10 to 15 feet but if you really want to put it on good go for 10 feet. I’m ordering two more cans. The product does look very good though, and I am pleased with the purchase, even though it is obviously quite expensive, but what isn’t nowadays?

Worked very well for me. Only thing you should know going in is that it dries to a very flat light gray finish. On some things I have top coated with Rustoleum dark steel and been very pleased with the outcome. I recommend this primer.

Difficult to review without witnessing how it protects with age.Recoat cut ends of threaded rod.

The best way to slow the rust on your vehicle. Notice the key word there, SLOW the rust lol. Unless you are literally taking apart your vehicle and sand blasting to bright steel, don't waste your money on the expensive, BS-filled "rust stopper" products that claim you can just paint over rust and it stops it completely. They don't work, period. In fact, many of the expensive ones just make the rust worse by trapping moisture behind the hard coating they leave which you'll find after your hard work starts peeling off in giant flakes.I used this stuff on my truck frame and over the winter, it took most of the corrosion from the salt. Now I can just brush that coating off and re-coat it before next winter.

I used this on the stainless steel rudder on my boat.

Used the spray can for about three minutes before spray nozzle and can clogged up, not allowing more spray. Had to be an old can. Not happy that you trust a company to send high-quality product and at a higher price because of Amazon and then it fails.

I have researched a lot and used many products for cold galvanizing before using ZRC. And to report all of them did not full fill my requirement. Specifically Rustoleum product. My experience with that one was bad at best. It was unable to seal a any open surface and if you scratch with you fingernail , it comes apart. On the other hand I found ZRC is much resilient product. I used is on some of the places where I was not able to reach and it might has loose rust hanging, but ZRC is able to stick to the place quite good. and it passes the fingernail test with flying color. This is just a initial review, and later I will comment how good it is to prevent rust. My expectation is not a small speck of red rust which Rustoleum failed very very badly. It(Rustoleum) makes feel my money and effort went down to the hole.There is one problem with ZRC, I could not find this product anywhere other than Amazon( not in Walmart, Advanced auto parts, oreily, Auto zone, or other local retailer) and the shipping of more than 8 bucks is not good. I am not able to figure out why?

First used this 40 years ago in an industrial situation on the gulf coast. Ive seen welds painted with this still in good shape when the pipe near it was heavily rusted. It may seem pricey but worth every penny.
