Monty, I used Rustoleum Professional also from Menards lol. It laid on smoothly, I let it dry a couple of days then wet sanded it lightly and let it dry good before putting on the color coats.I generally go to Menards as they have an exceptional array of paints, even your regular Testors model paints. In general, whatever brand paint I use I use the same brand primer & clear since I know it'll be compatible for the most part, at least I haven't had any issues by doing that.
