I will be replacing the cab (51 Chevy 3/4 ) sometime next week (with fingers crossed) and would like to do something with the underside to fortify it against rust and noise. I’ve thought about bedliner but don’t know how hard that would be to apply; I don’t have an air compressor so it would have to be applied via a brush. Is there a better treatment than bedliner? Does anyone have a suggestion as to what I can do? Also, any warnings/suggestions as I fit the cab back on?
