I have just had my frame and swingarm for my supermoto powder coated gloss black, and i must say i am 'as' impressed is i have been with other bike frames i have had done. nowadays you can have the coating done in just about any colour you want. i think there are a couple of different processes used, electric passed through or heat baked, i am no expert on the subject mind! mine was done with the latter process. they protected all threads and bearing surfaces from exposure. if u are having your swingarm done, press the bearings out as the oven melts the grease, stopping the coating adhering properly! i will post pics when i suss out how! hope this helps
