No, I'm not nuts...really!

I once painted the engine bay of one my Darts with a spraybomb, after cleaning/sanding. I had a local shop mix up two spraybombs of automotive paint. It went on great, and held up well for years (to the extent of the prep).

My brother sprayed his older Charger fenders with a basic red enamel spraybomb, and although it looked good for a year, it did oxidize quite quickly.
