Nice Pooper (Porsche/Cooper)! You did the stripes and numbers a helluva lot better than I would have been able to do with a brush! I would have had to print decals, and they would have looked like printed decals. The numbers especially look very 'in-period'.
I use auto lacquer for my builds - great stuff, but not so great on your breakfast cereal. I just put in new basement windows and I am going to build a vented paint booth that takes advantage of one of the new windows. You may want to check out
www.hiroboy.com. He has some good paint (not as volatile as lacquer, but goes on almost as well) with fine metallics and good coverage. Shipping should be reasonable for you as he is local.
