This information was most helpful. Apparently the Auto Air base will bind to fiberglass, Lexan and Carbon fiber just find without a primer. So all this primer nonsense has been somewhat wasted time.
The primer did help me fill all the pinholes and fix all the problems with the wheel pants. Better prep would have made it unnecessary. I'll sand the parts till they are smooth, if I sand through to the fiberglass its not a problem. On with the base coat tomorrow.
