Great question! Getting rid of truck bed rust yourself is definitely doable, but it is a somewhat intensive process—we’ve included a rough outline of the process below:
If you want to go the extra mile, you can use a chemical rust remover to ensure that all rust was removed—just make sure to follow the product instructions carefully.
At this point, you can either weld a patch on or apply a body patch to cover any rust holes in the body of the truck—we’d recommend the latter. If the rust wasn’t so bad as to have eaten holes through the metal, you can paint any exposed metal with a rust-preventative primer and repaint the area.
