Bax:

When I said "boils off a drop of water in a few seconds" I was referring to my usual temp for GLUING. I always glue down first, THEN shrink when I've got everything the way I want it (and you are right, it takes a LOT of heat to shrink MK).

If a newbie tries to shrink as they are gluing, at the temp you were referring to they might end up melting a hole or separating the color from the plastic (which sucks @$$) in the piece they are working with (speaking from experience here!)

Not arguing with you Bax, you provide a lot of great info here. Just wanted to clarify that.
