how do i get spray paint stick to zinc plated bolts without chipping off? I tried Rust-Oleum 249322 Automotive Self Etching Primer but it still chips off.I could heat up the bolts with a torch to melt the zinc off but that is a last resort. Any ideas?
I bead blast the heads of the bolts but not the threads. Then poke holes in a sheet of cardboard to hold the bolts and paint em.
rough up the surface like bead blasting guy saidor powder coating
wirebrush on a drill
Mix pigment with epoxy and paint with that.

Go to a paint store. Look for etching primers for galvanized metal
