I plan to paint my 50 grille but unsure what method is best.I am not building show pickup but don't want rust to appear after painting. Do I sandblast grille intact and prime and paint? OR do I dissemble prime and paint? If I take grille apart what fasteners do I use to reassemble? Do I use nuts and bolts,sheet metal screws, or is there a kit available with some type of rivets.
