Sounds like a good method, but im short on boilers. However, i think next time i paint ill do it between two pressure cookers just before dinner. Sweet parts and wife points for cooking.

The best success I have had with rattle can painting was the first time I ever tried it. I used Rustoleum cobalt metallic blue...any metallic blue would have been fine though...but the key was the primer and clear. For the primer I used Plastikote self etching, to this day I have yet to see a primer be so compatible with everything I have thrown at it. The clear coat I used was VHT and it was meant for brake calipers and aluminum rims. I used this combination on my old Westcoast pipe and my ski's first paint job, it held up amazingly well. As far as I know it's still on the pipe and it has been over 5 years now. Since then I have had absolutely horrible success with clear coats and paints reacting to primers on the ski...I will be on paint job 4 or 5 by next spring, I can't remember now I seem to be doing it so often anymore lol. Rustoleum primers have reacted with Rustoleum paints for me almost every time. This year the paint actually cringed and wrinkled into cords from reacting against the Rustoleum primer in addition to the paint spraying out from under the nozzles. The little well under the red spray nozzles would fill up then the air vortex from the compressed air in the can would pick up the paint and shoot splotches everywhere. Nothing more frustrating then doing the job 3x an hour. Fortunately Lowe's took back every can of paint that failed like that and refunded the money under a quality issue. Apparently Rustoleum takes a lot of concern over this so a 150 dollar paint job ended up costing me about 60 bucks 
I've had good look luck with VHT paints. The purple piece by the PTO is anodized purple paint. It matches the anodizing on the head, carbs, and intake well IMO. The burnt copper is also VHT and I was less than patient with it and it still turned out OK. The engine was sandblasted before painting.
