After getting a nasty freeze/burn closing the bleeder valve on the propane
tank on my Westy yesterday (operator had not gloves or pliers handy) using a
glove I thought would protect me and didn't, I've been looking online for
gloves I can carry that will protect my hand closing the bleeder.  But I'm
not finding anything that appears to have a vapor barrier to it plus some
insulation from the cold.  I was burned because the venting propane came
right through the glove.
So what kind of gloves should I be looking for? What are they called,
assuming such exist?
