RE: Paint compatibility help please!!
Well, the Krylon through the airbrush did and didn't solve the problem.... I discovered that solvents or no solvents, the problem I was having was too heavy a coat over the other paint chemistry. So, about 5 really light coats did the trick & covered without bubbling, etc. Fortunately, the Krylon paint is thin enough to let you get away with thin coats & not get a rough finish (the small droplets really flatten out well).
So; remember to try THIN COATS if you run into the same problem. This had me hung up for three days!
