Just to add to the confusion
I had my swing arm blasted and painted black. The frame was blasted and painted red, the wheels were rubbed down and painted red. The finish is great and now 18 months old.
Cheaper than powder coating and less hassle. May not be as durable as powder coat but ok so far. If I've still got the bike in a year or two and it's starting to look scaby I'll just have the parts painted again.
