Never tired it with a firearm but I have done a fair share of auto body work. Properly degreased, spot and glazing putty plus wet sanding with 600 grit will make that revolver slick as snail slobber. Then one of the spray-on finishes used on firearms for a topcoat. Might turn out well.
I doubt that I will ever try it but some here might be inclined to do so.
