I'm looking to clean up the rust on some of my bunk supports and repaint them in gloss black. They all have 90%+ of the steel left and I would like to keep it that way.
My duck boat trailer my son and I sand blasted it and painted it with Rust Oleum from the gallon can not spray cans. It only lasted about 2 seasons and started rusting again, I don't know maybe a bad batch?
So what has anyone else used the has held up?
I was thinking of maybe a catalyzed urethane auto paint
