Here in Seattle we have a lot of rainy days.  Makes it really hard to prime models during the wet season (October-June).  I recently picked up some Vallejo Surface Primer which can be put through the airbrush to see if that would work.  Tried it out tonight and it’s absolutely fantastic!  I did have to up my air-pressure a little bit to spray it without blocking the airbrush up, but it goes on super thin and smooth.  The best part is that it comes in a variety of colors to make painting easier.  There is almost zero smell so the wife won’t be bothered by the freshly sprayed models either.  Highly recommend.
