In my effort to refinish a Mossberg M46 22LR stock and remove the old cruddy varnish and scratches, I came into a dilemma. I was nearly finished with the sanding progression when I reached for my rag to wipe it down. Well, mistakenly I picked up the wrong rag which was lightly dried with a mixture of Tung and MS, from another stock project. I had the intention to finish it with Tru-oil to match my other 22 Mossberg M42. Although it was an error the stock looks beautiful rubbed down, however, here lies the problem. The wood isn't that hard, I'm not sure but it looks like walnut but scratches and dents easy. Maybe that's why the sanding didn't take long to remove most of the surface scratches. My question since the Tung formula is rubbed in can I add the Tru-oil or should I mix in a varnish to strengthen the finish coating?
