Not only does heat soften the epoxy for removal, it softens it so that you can take a composite wing that is warped, heat it and then hold it in a new position and the epoxy or resin will take a set in the new position.

The AMA 424/428 guys have been doing this for years!

Try it you'll like it.
There's a write up on wing warp at Darrol Cady's site:
