Coating the bulb with Teflon involves coating the inside with a Teflon
liquid aqueous dispersion, letting it dry, and then curing it in an oven
at 380 to 400 degrees C for around 30 minutes while circulating dry air
through the bulb.
A little bit intricate but doable. Main concern is getting the bulb
surface absolutely clean before coating.
A hydrofluoric acid rinse is a must!
