If your gun stock has checkered areas, apply Lin-Speed Oil to these areas right after completing the inletted areas. Dip an old tooth brush or similar stiff bristled brush into the Lin-Speed (again, put a little Lin-Speed in a separate container) and push the product throughout the checkering. Using a semi stiff bristled brush will help prevent the checkering from getting clogged with finish. Again, a little Lin-Speed goes a long way. The excess Lin-Speed from the checkered area can simply be rubbed into the smooth areas around the checkering. Only do one or two very very thin applications in the checkering so as not to clog the checkering with Lin-Speed Oil.
