Worth doing yourself some places don't worth asking them first .if your getting wheels done get the bearing areas masked along with area the discs bolt onto saves a lot of hassle .if they do bike parts regularly they should do so as a matter of course would check with them.

I had some spoked rims powder coated a while back for my cafe racer and they look really good but they didn't mask off the bloody disc faces! I fitted the discs just to see what it all looked like and one had over 0.5mm run-out just from the coating.
Took quite a while to get off with a Stanley knife blade and some emery cloth.

Yes i had the same problem, if i ever get any done again they will be taken to a motorbike powdercoaters in Yorkshire who do a good job. They aren't cheap but all the stuff I've had done by them was very good and surfaces/threads were masked off by them before powdercoated

Other thing worth noting is that powders can't be mixed like paint can, so you usually find colour options far more limiting. I had some wheels powder coated "gold" but they only had a choice of two which wound up looking like shit mixed with milk rather than gold!

Had them re-sprayed in 2k paint to a colour mix of my spec and now they are perfect. Arguably not as durable but still pretty hard wearing

I always do, it's easier. I also mask with duck tape anywhere I don't want powder / blasting rather than leave it to the blasters memory. They'll remove it after blasting and replace with a different tape when coating.
Also, make sure there is no grease or oil inside the part. When it goes in the oven it will leach out and ruin / bubble the finish.
