Type of paint to use??

[crumbaa]

Restoring my grandpa's 30 Cabriolet. We are doing going ground up frame off but not planning to build a fine point car. Plan is to build nice driver and make it as close to true stock as we can without braking the bank. We are not planning to go back with original colors. Wheels, body, stripe will be “storm gray metallic”, it s dark silvery gray, black fenders, rear upper body, and top. I do not know a lot about paint and the choices are a bit overwhelming. From what I have read lacquer chips pretty easy and does not hold up very well, Enamel seems to be better than Lacquer and I can't find many comments that say there is a down side for enamel, I had a cutlass in the 70s with water based paint the came off the car in sheets, urethane seems to produce the best overall results. Given that we are not going for fine point do you have an opinion as to the best overall paint to go with? There is also the question clear coat, is this just a matter of preference or is it something that makes the finish last longer? We plan to have it painted so complexity of the paint system is not really an issue. Thoughts? Opinions? Any advice you have would be appreciated.
