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

Dartnut's answer is about the most open minded, yet factual response I could imagine. If you are spending time to prep this car right, I'd paint it with good product. I'm spending over $1k in materials and supplies to paint my '73. I just keep reminding myself that a new Challenger (most comparable brand new car, IMO) would start at $26k in SXT trim, so I'm getting off cheap!
