I use Dura-Coat products to refinish firearm metal. This product was developed for firearms. The first step is to strip down the firearm and completely clean all parts. Then your firearm is stripped of its old finish, down to the white. (Bare Metal) This lets the Dura Coat bond real well to the Metal. Then the Dura Coat is applied. When it is done all your letters and numbers will be sharp and readable. I have Four colors in stock that most people have there gun done in. They are HK Black, (Semi Gloss) Flat Black, Gun Blue and stainless. There are many colors to choose from, so you can do them just about any color you can think of. It only takes a couple of days to get something not in stock. Prices are from $75.00-$150.00 for most guns. I do not do Winchester model 12’s or 97’s. They are just too difficult to get them back together with out scratching and marring them.
