Hook I have used a weird mixture of Hydrogen peroxide and cleaning ammonia that kills lots of stuff. And the user if you mix it with the wrong thing. But that has cut a lot of things for me. No guarantee it would do anything on that old plastic stock finish. That is a more than tolerable finish you have there. This stock Renegade 50 is doing is good that it is a temp. But I would be challenged, at this point, to install the walnut this winter then hit the old thing again. Be Well, RZ.
