Dear Sam,
	Perhaps your friend was mistaken and said epoxy rather than hot hide glue.
 The hot hide glue is a method I have used in the past for removing the
finish on soundboards and sides of bridges.  You brush it on with a 3"
brush and let it dry.  When it dries it pulls up the old finish like onion
skin.  It is scary at first, but it really works
