A couple of notes on Kroil.  First of all, you can order it in small
containers from Nancy Fratti.  I bought one several years ago and it's
lasted me a long time.

Secondly, I wanted to remove the pulley wheel from my Duo-Art pump.
I first heated the area with a torch, then applied Kroil, let it sit
for a couple of hours, heated it again and I was able to easily remove
it.  Before adding the Kroil, it wouldn't budge even with heating it.
