I know this probably has been answered a couple dozen times here, but I'm not having any luck finding some basic answers. I've sprayed the body with Duplicolor flake paint - - three coats as recommended, all good so far, no ugliness has appeared yet. Humidity, temp are all good. Do I need to start the clear coats while the color is still curing? Or is it better to let it gas off a bit? For how long? Would you go for more than three color coats, or leave a sleeping dog lie?
