It is for the heat, not the paint.
I thought of putting on one of those pencil gripper thingys on. The foam kind that are about 1 1/2 to 2 inches long. Usually made of bright colors.
I think the heat could be insulated very well, and not burn or even be hot to the touch. They might look silly, but will perform a very useful function for us vapors'
What do you think?
