Can I thin Testors Lacquer clear flat with regular enamel airbrush thinner and then spray over future coated aircraft? Or should I use lacquer thinner as recommended by the clear flat directions for use? I tried brushing a little of the clear flat on a part painted with acrylic and some of the paint came off onto the brush. I don’t want to spray my planes and then mess up the paint and weathering I’ve already applied.
