Radio South used to sell PPG automotive acrylic enamel in smaller quantities (pints). I always had to buy at least a quart of paint when puurchasing from an auto paint supplier - which lasts forever if you're just using it for trim colors!!

I accidently discovered the ability to monokote over fiberglass about 25 years ago when the paint I purchased (had mixed, in fact) didn't match the monokote. So I decided to try to monokote the cowl and wheel pants. At little tricky at first, but the results were quite good. I did clear coat to prevent monokote peeling. Lasted several years of flying. Didn't matter much on the final crash...[&o]

Painting 'light' isn't difficult, but it is very easy to spray on more paint than necessary. Just enough for uniform coverage. Good lighting is essential!!
