I spent 5 hours yesterday with a pocket knife, gently sliding it between the finish and the wood. It just lifed right up off the wood. I have a huge pile of plastic chips lying around. However, you cant see anymore poly finish on the body.
Granted, I havent taken the guitar apart yet. I still need to get the poly off under the pickguard, bridge plate and neck plate. I have a gig saturday, I'll play the guitar "nude" for that and get back to work on saturday.
I took a few pics, I'll post 'em later.
