91% alcohol should strip the paint after soaking for 24 hours. I stripped one exactly like this recently. 91% alcohol can be found at your local pharmacy, Wal Mart, even grocery stores. Regular rubbing alcohol, which is only 50 to 70% alcohol (depending on brand) won't strip the paint. Place the body in a container large enough to permit filling with 91% alcohol that completely covers the body. A container with a lid is best, but you can cover it with plastic wrap if you don't have a lid for it.
