Who has painted their engine with a spray gun?

For over 40 years I've used every rattle can paint out there. VHT, Plastic Coat. Mopar, etc, etc. The fact of the matter is that rattle can paint doesn't have nearly solids that mixed paint does and no hardeners.
A friend turned me onto this years ago and it was like OMG this is sooooooooooo much better. Also get much better coverage from a gun. Even a good enamel from a gun is much better but I really like the urethane stuff.
