Upon looking a little closer at the bottle I was indeed using FS 30538, I did not intend to spray flat paint. I mixed the paint according to Donn Yost's video on painting models, 2 parts paint to 1 part lacquer thinner. I was using a .04 mm needle with the air pressure set at 30 psi. I do know not to pay a lot more attention to Testors paint codes on the bottle!
