I can't answer on the masking because I have always left mine on till after cure.

The powder sticks rather well considering. It takes a little effort to knock it off. I bought a cheap roll of safety wire from the parts house, that I use to make tie offs to the part. It can be bent to get minimum contact with the part. Then use small s-hooks from a hardware store to hook the wire to the rack. I have accidently bumped the part putting it in the oven. Most of the time it is not bad and the powder will cover when it begins to flow. If there is a large bare spot, it is not hard to touch it up before curing. If I have alot to do I'll powder a part and hang it in the oven while I powder the next. I'll do this until the oven is full, then cure.
