My frame on my '93 is rusting but not any rot just yet.. However it looks ugly from a far you can see the frame and see that it is rusty.. Any advice on spray painting the frame of these old jeeps? Hit it with some POR 15 first? Or just got over it with Rustoleum? Has anyone painted their frame?
If none of it is rusted through make sure you sand down the area until it is clean then apply your choice of rust preventative. Use some sort of solvent to make sure there is no grease on the area. Don't just paint over it the paint will lift and you will still have rust underneath.
Eastwood Company sells a great metal restoration spray. After you knock the rust off spay the frame down. Make sure you spray on the inside of the frame. Prime it them paint it. I did the frame on my 93 and sprayed it with a spray in bed liner. The metal restorer works better than POR-15 and is a little less expensive.
I wire brushed my frame and replaced rotted sections then primed with Rustoleum primer followed by Rustoleum and still have rust appearance issues. If I was to do it over I would have done POR15.
Where you located? Rust belt or humid climates require more prep. Here in the SW, you can just rattlecan a non greasy frame with krylon rust-tough and call it good
Restoring a 66 f100. Finished the frame a year ago. Researched everything up and down.. Went with por 15. And eastwoods black frame top coat. Will last forever. But I'm sure it's not the only way to go, I'm on Long Island and took the weather conditions and winter salts in consideration before I did anything. Best of Luck!
