Hi all, in the next two weeks coming i will be taking the box off my truck and cleaning up the frame. starting to get more rust coming through / paint chipping off. Can any of you recommend a real durable paint I should use on my frame? I am thinking on cleaning it with a wire wheel / maybe mini sand blaster and then using rust reformer and following that up with two part marine grade paint. The type of paint they use on industrial ships. Anyone have any recommendations or what to use when i goes at it? Also gotta take the box off anyways because im doing a good " backyard " paint job to the truck. Its a cheap truck and i want it to last another 5 years or more hopefully.

 

Por15 is a good paint for that,but wear gloves, it's hard to get the stuff of your hands.

 

Yes, get off as much rust as possible then use a "rust reformer" like naval jelly, these products change any remaining rust to an inert compound but just on the surface.

Yes, you need a primer because "paint" can't stick to metal very well, primer can but primer can't take sun and rain
Paint can stick to primer, so the paint protects the primer, lol.

Metal rust is oxidation, any where oxygen can touch metal rust will start, water speeds up the oxidation process, and salt(minerals) speeds it up even more

The benefit of Paint is that it cuts off the oxygen in the air from touching the metal

And yes, rust is the same chemical reaction as fire, just a slower oxidation process with metal than with wood, lol.

 

Just did this recently. I used Gemplers Rust Converter $20 a quart and it worked very well. Just knock off any scaly rust and apply it with a spray bottle and a cheap paint brush. Makes a solid coating that takes a top coat extremely well. After the rust converter cures for 48 hours or so just top coat it with an oil base paint (Rustoleum). I am very impressed with the results give it a try.
