It's just a handle, after all...
My guns are pretty much safe from theft for pretty.
A couple even have nicely grained wood. When I can't hunt 'em anymore, I'll spiff them up. Maybe.
Spray on takes some fine technique and a dust free environment- BTDT. Nowadays I settle for hand-applied, reasonably good looking, but PDG water-proofing.
They all (well most of them) kill quite nicely to 500 yards, looks be damned, thank you very much.

Multiple hand-rubbed finishes always worked out best for me, back in my gunsmithing days.
