Thanks,May have to try this.Brownell's........ALUMA-HYDE II 12 oz aerosol $12.99. This is a tough finish, easy to apply. It won't fill in deep pits but it does wonders on small pits and making the metal look better. Not for high grade guns but more for low value type guns and military surplus. There are different colors. Sticking with one of the matte colors (eg, matte black) will do the best cover-up. The secrets are to clean the metal meticulously and spray in light mist coats rather than trying to do it all at one. Brownell's has videos on application.
