Is it paint or wax?
In days of old, to help weatherproof our revolvers, we used to wax them, and the white stuff collected in all the nooks and crannies on the revolver, hence "highlighting" the letters and emblems. Most of us just left it there, and we'd add to it the next time we waxed. I used plain old everyday automotive Turtlewax on those days, and it helps greatly preventing a lot of rusting on the surface of the revolver, in highly humid areas of the country. It seems getting in and out of an air conditioned patrol car caused moisture to condense on the surface anything metal, and your revolver was the least protected item. Anyway, the wax method was a common practice anywhere along the Gulf Coast in them days of old. That's why I prefer stainless steel guns these days.
