Has anyone had experience powder coating a rim? I want to powder coat a dull black. The questions are:

1.) I am guessing the area under the spinner has to be kept bare.
2.) I am guessing where the rim sits on the rotor and the pin holes also need to be bare?
3.) Having very little experience with powder coating I assume you can "tape off" areas like this?

Any information is appreciated, I am in the initial stages or researching this.
