When applying cerakote (or like finish) to an item that has engraved writing or other small, sunken niches that you don't want to coat (for example, the writing on a Schmidt & Bender scope, or the tritium hole in a night sight), how do you all cover these parts of the item so that the spray doesn't hit it, and you can remove the block after the curing is finished?
