I was informed by a guy at Performance Car Graphics about a paint. Partial quote...

"Our experience over many years with black crinkle:
-Krylon is thick, inappropriate, and unattractive
-Eastwood is mediocre or good or fair for appearance and originality. Very sensitive to thickness of costs, lapse time between coats, temperature, brightness of sunlight
-Plastikote is most reliable for all of the above factors, but you must practice first. Even-nes of coats, thickness of coats, and temperature are critical. Plastikote 217 Black."

I haven't tried it myself, so I would like to hear experiences.
