I have solved the problem I discussed in the original post as follows. Originally, I was having trouble with the combo of Vallejo acrylic paint, Tamiya spray gloss coat, then Tamiya panel liner, cleaned up with testors enamel thinner. I solved this in a bunch of ways. 1) I started using primer more religiously 2) I stopped using Tamiya has my first/decal gloss coat and switched to pledge/future. 3) I use Mona Lisa odorless enamel thinner. I still use the panel liner and it works pretty well now.
