I have just sprayed a coat of Ammo of Mig grey acrylic (straight out of the bottle) over a primer coat of Tamiya fine light grey from a rattle can.
The acrylic went all splotchy (took a photo and saved it to my computor, but cant figure out how to get it in a post) and I'm not sure what the problem was, too high a pressure (about 30psi) or the base coat.
Any suggestions?
