I wondered about that too, seems like a good way to burn your fingers with a lighter..

Years ago they used to use pure Bees Wax on turbine bolts.
Heat, apply wax, let cool and remove. It protected them from galling.
Today we have much better pre-lube that stands up to the heat so it's still there when they're removed after years of heat/cool cycles.

your just racking them up Chuck
