Re: Dura Coat?
Bead blast and re-blue, KG GunKote, Ceracoat. GunKote & CeraCoat are a coating , so they help 'seal' the surfaces, that are coated, from the elements. You still have to take care or the un-coated areas such as the bore, ect., ect. Bead blast and re-blue has the same corrosion protection bluing has, not much, needs to have a coat of oil or light grease for best protection.
