Yesterday I treated all the rust patches in the floor frame. There was actually quite a lot and the more of the white paint I ground off, the more rust I discovered underneath it! At least it was all still pretty minor and I didn’t stress too much about getting it all off. Just did the worst of it.
Some of the rust before:



After grinding back most of the rust:


After that, I painted the whole frame with Penetrol, which soaks down into every little crevice and seals up the rusty metal. Once that was dry, I then painted the floor frame with two coats of Rust Guard primer mixed with more Penetrol, and then finished with a top coat of Rust Guard enamel.

It was a lot of work to do this, but I am so pleased with the finished result. It looks AMAZING!
I can now be confident that I won’t have to worry about rust in my subfloor for a very long time!

Hi
Did you paint over the original paint with Penetrol and then the 2 coats, of fid you grind ALL of the original paint off first?
Thank you in advancd

I only ground off the sections that had the rust. The rest I just painted over the original factory paint coating.
Thank you Dyani
