Go to a small powdercoating shop, one which does custom auto parts and firearms. The owner of the shop I went to did the spraying. He knew how to protect gasket surfaces and hydraulic fitting threads. I pointed out the areas I didn't want sprayed and they did a great job. I didn't really tell him anything he didn't know and he showed me a BMX bike frame he had done for display.

Do not go to a large job lot shop where your bike frame will be mixed in with three hundred washing machine lids or a production run of lawn furniture.

The powder coat on my bike wore through where a cable rubbed on the frame - no surprise as powder coat is plastic. It has resisted normal bike chemicals - degreasers, lubes and perspiration. A derailleur hanger clamp had no noticeable effect on the coating.
