i need to paint my door frame on the trailer. it gets way more abuse the most. what do you sugest? i waas thinking rough it up with some 220 sand paper, prime it and rustolium it. any other sugestions?

You should not experiment... Go to some professional painter.

Either that or POR-15, dries rock hard and doesnt let rust in

POR15, Inc. - Stop Rust Permanently - Repair Gas & Fuel Tanks

thats my first choice but they dont make it in white.. nor grey.

OK then Rust Bullet, comes in silver, pretty much the same stuff as POR 15

Summit has it, stop and pick some up next trip, and try not to buy anything else while you're in there.................LOL

great.. last thing i need is to go in there.. lol hope they got white. is primer needed with it?

I think you can paint over it, any kind of paint

Rust Inhibitor Paint & Corrosion Converter Remover ? Rust Bullet

thank you sir.
