I've been dabbling with it this winter. Started out using the Brownells aerosol KG Gunkote to refinish some alloy bottom metal, then got an airbrush and went whole hog with NIC heat-cure Cerakote. I already had a sandblasting cabinet and an old oven I could use.

Basically you detail strip, solvent clean, sandblast, degrease, spray, and bake. Hardest part was learning how to spray without fisheyes, runs, and blotches.
