Who has painted their engine with a spray gun?

Kern Dog said

Since I have my engine out for a rebuild, I'm thinking of painting it with a catalyzed paint from a spray gun. Despite good prep, my engines seem to peel a little in some areas so I thought that better quality paint might stick longer.
The spray can stuff is cheap and anyone can paint with it. The lack of a hardener means that the shine often fades in a few years. It would be great to have this engine look great for more than a few years.

First get all the old paint and primer off the engine.
Surface perp is crucial to sucsess if you think you have it clean check it with a clean white cloth, and do it again. The best degreaser paint prep bar none is VM&P Naphtha. Wear gloves and eye protection, vent with a fan.
Scuff all aluminum and machined surface's.
I use Von Sickle implament paint and their hardner, its a high solids paint, very durable and it is very reasonablely priced. No primier required
