The nitrate gun stock stain marketed by Kibler's is easy to use. Apply, let dry and then heat it the wood to get color. I do suggest that first time users practice on a piece of scrap piece of wood to learn how to modulate the heat the source being used. The wood can be scorched and care must be taken at edges and thin areas of wood, otherwise, burnt edges result. Once the heating process is complete, this staining system allows the user to buff the stock if the color is too dark and lighten the color up a bit.
