I would agree with you Mike, but my surface is smooth. And this was sprayed with a Grayco unit, one with a hose 1" in dia that comes from a heated turbine compressor. One of these units with little pressure, lots of volume. Well, I guess that could pump moisture too, but I have had the same thing happen on the door with an HVLP sharpe, although not to quite the same extent. I thought this 2 stage stuff was suppose to be easier. This is my first car with the two stage....and it hasn't been working out.
