Rust treatments

[mstaley]

Has anyone ever used POR-15 or similar products? What kind of success did you have? I'm looking to coat the frame with it. How clean does the metal need to be? I have power washed an degreased the frame. There is no loose rust. The rust that is left is rough texture. Feels like coarse sandpaper.

What I do is treat the rusted areas with Ospho. It kills the rust so it won't start again so quickly. I sand, wire wheel or sand blast the area before the Ospho treatment to remove the big chunks. After the treatment with Ospho, then just prime with a good quality primer (not krylon or rustoleum), I use Gillespie, and paint.

i have used POR15 and am happy with that product also, used widely by car restoration people.

I've never used it, but i know some people have a hard time with the por-15. Seems like the biggest thing is prepping the surface, making sure to do exactly what it says to do. I've heard a few stories about peeling, but i think it was due to bad prep. Mostly good things about it though.

I used POR-15 on my frame and I have nothing but bad things to say about it. I prepped the frame exactly how the instructions said. But it started to peel and flake off after 6 months. I called the company and they said since I was so close to the ocean the salt air affects the POR. So they gave me my money back. I cleaned off as much as I could and used Ospho like kwai said. I made sure to use it during the rest of the resto-mod and after 8 years all is good.
