100% Mineral spirits is fine if you have 100% Poly or other modern Varnish finish on your gun stock, but a traditional Linseed or shellac type of finish will at the best will be removed or softened and at worst your gun stock will look like the surface of the moon. All my working life I have kept these words in the forefront of my mind "Professionals designed, built and sailed, the TITANIC NOAH was just an amateur". food for thought the only difference between an amateur and a professional is a professional gets paid for the work it does not mean it is any better than an AMATEUR'S efforts.
