How do you guys prep your stocks before finishing? I'm starting to refinish a few of the plain stocks I've purchased before I move onto the nicer ones, I've been applying citristrip to them with a paintbrush, letting them sit for a few hours then scrubbing them thoroughly with a soft bristled brush under hot tap water (as hot as I can get it). I've then been setting them in the sun to dry. It does a great job, and removes most of the dents (hot water I imagine) but I'm a little worried about the stocks warping or twisting. I figured that it isn't terribly different than steaming it, and it's nice because it's really fast, only takes a few minutes of scrubbing with hot water. These stocks don't have any cartouches though. Anybody else do it like this?
