heat gun on a slab coming out of the oven is not at all unreasonable.

certainly dumber than going at a jar of pentane/hexane with a heat gun, but not by a whole lot imo.
I guess I’d rather have folks sans clue be more cautious than less cautious, but I’d prefer they just stay the hell away from the entire process.
