My 2 cents about Restoration shop paint. I have used the black single stage Acrylic Urethane to paint a car trailer 5 years ago. left in weather, hot California summers it is just now starting to fade. will be repainting it again this year. Recently used the the same product to paint a 64 falcon . its easy to shoot , cuts and polished very nice if you get run or some dust in the paint. have used the base coat clear coat Urethane and the Lacquers as well in TCP Global's standard colors , found them not to be a close match to the factory colors, such as viper red corvette rally red. good for a complete repaint but don't try to use these colors for a spot repair of factory paint. TCP global doesn't package paint very well for shipping, I have received dented and leaking cans and had to argue with them to get the products replaced even when I had bought the shipping insurance. They asked me to open the can and see how much leaked out and they would send me that much paint . After several phone calls they did finally send me another gallon of paint, shipped in box with no padding received it dented as well but not leaking.
