Best finish to repaint Ak don’t really need it but just need a project. I was thinking DuraCoat or the finish Brownells sells. Also any pointer such as what areas to tape off, don’t think I’m going to spray inside the receiver. Just need help besides the cleaning and degreasing. Should I put sand paper to it or just spray over and also I’m thinking either to keep it black or fde since I ordered a m4 stock adapter and ultimak.
