Lots of good advice here. DON'T use MEK though, it'll strip everything off the stock. I worked at a place in the 80's where MEK was used a lot and that stuff will eat up all kinds of stuff plus it's HIGHLY flammable & explosive. It caused one HELLUVA BOOM and fire when I worked there, I helped put the fire out before the fire dept got there and took one of the guys to the hospital with 2nd and 3rd degree burns.
