What type of finish do you put on your underhood nuts and bolts? Im mainly concerned about corrosion protection but these are some of those little details that need to look right. Ive been thinking about a zinc plating kit from eastwood but you have to "clear coat" them after plating them...wtf? Ive tried painting bolts dull silver in the past but never been able to keep the paint from getting chipped up when tightening the bolts. Is there a trick to that art? Running out and buying stainless ones is not an option, this is more "restoration" work. Looking for some ideas here.
