The Stovebolt Site Forums The Shop Area Paint and Body Shop POR 15 vs Rustoleum

I have used Zero Rust and POR 15 and top coated both with what ever color paint I wanted to use. I could be wrong or it might just have been the batch of Zero Rust I was using but it was not as strong as POR 15. I wish Zero Rust was because it is cheaper to buy. I have some pint size cans, and some quart size cans. I use the size can that fits the job I'am doing. That way I don't have to worry about storing any left over used can and it drying up. I use latex gloves doubled up and wear a long sleeve shirt when using either Zero Rust or POR 15. I never spray POR 15, not saying that you couldn't, but I don't have access to a Army Chem suit and I like to breath, so spraying POR 15 with just a 3M repirator is a no no. I have sand blasted and then applied, and I have just knocked off most the loose rust and applied the stuff. It just depends where I was applying it at. Under the fender wells, I just knocked off the loose rust and it holds up great, after all the instructions tell you that it holds better to that kind of surface. I always use the metal clean and surface prep that POr 15 supplies before applying the POR 15 and I have never had any problems with it. As far as removing the stuff, never had to and hope I never will have to, good luck to anyone that needs to remove it.
