Chapstick? That's a new one on me. Hey, if it works....

I disagree about clean up. Granted, if you just try to wipe the excess epoxy away with a rag you will just spread it all over. BUT, if you dampen the rag, paper towel, etc in alcohol (I use methanol found in the solvent area where paint is sold), it works really well for removing excess epoxy and is a lot easier than picking the stuff out after it kicks off. If you don't have access to methanol, the peeling up of the expoxy works.... I've done it before. The key as A.J. mentioned is that you must get to it while it is rubbery, i.e. the epoxy has kicked, but is not fully cured.
