    I'm having a welder repair a bunch of rust issues. Need to then give it a paint job. But not crazy about spending a ton of $$. Any DIY tips? I'm gonna paint the entire bed.

    I once painted my old GMC dump bed using black Rustoleum in spray cans. I believe it took about 14 cans, and one of those "spray triggers" you can purchase for cans of spray paint. I also used some old moving blankets to cover the truck cab, which was white.Took me a whole afternoon, but looked good and was way cheaper than having a paint shop do it. Just be sure and pick a fairly calm day if you do it outside like I did. Wind is not your friend.

    With mine, I would first wire wheel the surface. Then I would brush on the paint. 2 coats. I would do this once a year. Original dump box lasted 17 years. It seen alot of salt as it was the truck used to fill bins. Needless to say it seen its share of patches.

    . I had a lot better luck rolling on the Rustoleum liquid paint and then using the cans to spray the places you couldn’t roll. And the liquid is a better value.

    This and use those little 4 inch foam rollers. Sometimes I will thin the paint just a little bit

    Prior to painting, neutralize the rust with phosphoric acid.

    Many years ago I had a Datsun pickup which was developing extensive rust in the bed. I used a product called Rust Mort, made by SEM, prior to applying paint. I never saw rust in the bed again even though I had the truck for proably another 10 years. I have used a couple of other products that make claims to stopping rust, but none of them worked like the Rust Mort. The active ingredient is phosphoric acid. You might have similar results at less cost with a generic phosphoric acid.

    I have had great results by rolling on oil based paint (Rustoleum or others).
