I used Solartex on my BUSA DR.1 and painted with Latex using several types of brushes one of them (black foam one) and airbrush by adding Floetrol to the paint and also water to use in the airbrush. Both methods turned out perfect and no, you could not see any brush marks when I used the foam brush. I really love the way the Solartex and latex work together. Hope that helps!
