Lacquer thinner. Won't hurt glass, but don't get it on any painted
surface, or plastic. I haven't come across anything that it won't
dissolve, remove, clean, etc. Lacquer thinner is the only thing that
can remove the very nasty PL-premium adhesive (and probably also
expanding foam) from your hands before it dries.

Something else that might also work well in your case - gasoline.

In both cases, just a teaspoon full on a folded half-sized paper towel
or rag is enough.

I've used some urethane caulk, the stuff used to build school buses.
freight train cars or used in fender well/trunk seams of automobiles.

Choices are chewing it off your hands or repeated use of a pumice
stone in the shower. Get it in your hair and the only solution is to
clip the hair out.

Get in one your clothes - well it _never_ comes out. BTDT.
