robricc: I call it a hair dryer around the shop for obvious reasons. I assumed everyone would catch my drift.

Well, I for one didn't know you were a punk hair stylist!!

I can get the tubing here for nothing

I suppose another overkill approach to this would be to sink the whole assembly into a Tupperware vat of slow-curing, black pigment-laden epoxy. Just don't ever move!
