I paint with Vallejo paint by brush. Then I use Testors Glosscote to seal it. Then apply the Tamiya Panel line wash. The problem is trying to remove the excess panel wash from the surface. I use Testors enamel thinner on a q-tip to try to clean it. I must be doing something wrong because it NEVER works. the thinner doesn't remove anything at first, and by the time it does remove the wash, it removes the glosscote as well and damages the acrylic paint layers too. Is something in there incompatible with something else? Is there something better to use than a Q-tip, because the cotton tip falls apart so quickly as to be useless. I have no idea what I am doing wrong so ANY insight will be very helpful.
