I get the DuraCoat from Brownells http://www.brownells.com/gunsmith-t...aerosol-paints/duracoat-paints-prod44374.aspx Item # 100-007-936WB. You mix the paint with the activator and a small amount of their thinner. I spray it with an airbrush. I spray several light coats and let it dry at least 24 hours. This is basically an epoxy finish. It is pretty hard, but it can be scratched. I don't think they have it in spray cans. I believe the spray cans are a propellant to be used with a simple airbrush. I hope this helps.
