Thanks Wolf. The Tamiya white surface primer was smooth. After decanting the paint and letting it set a few days is was still pretty thin. So thin that it needed no thinner. I sprayed it at about 20 psi with 3 light coats and two med coats letting it flash about 5 min between coat. The humidity that morning was 56% if memory serves me correct. This was my first time decanting paint and shooting it through my airbrush so I was not sure what to expect so at this point I'm not sure what happened. Maybe the TS paints like to go on wet instead of the way I sprayed it.
