I still use spray cans quite often too. My experience is that the Tamiya spray cans really are the best. They have the nicest spray and go on smooth and thin. Some of the more generic paints can be a little thick and 'globby' so be sure to test them out. Many people swear by Duplicolor, Krylon, and Plasticote brands and I've never really had any significant trouble with them. Gip's right though, find out if it's a lacquer, and if so it's a really good plan to put down some primer first. I've actually gotten into the habit of priming everything, no matter what the paint. If you find a good brand, stick with it. It's nice to have a predictable result so you don't have to continue doind 'test' shots everytime you have a new brand of paint.
