HiDesertmodeler and oldermodelguy,
thanks for the info. Like many "vintage" modelers I have a stash of old Model Master enamels that I am working my way through. That being the case I will likely make another effort soon to learn the mysterious ways of airbrushing acrylics. My one and only attempt in the past was the old Acryl line and that was in a very dry/hot climate. That was a quick and less than successful adventure. Thanks to FSM and other forums I feel I am now a lot more educated about acrylics and there are also a lot more options available. I have hand brushed some of the Vallejo paints and thought they were great.
