It was maybe between 40 -50 percent humidity which isn't too high.
BTW, what do you use to thin Testors acrylic clear?
Crowe-t. I use both future or Testors acrylic thinner depending on the finish I want. I was thinking that perhaps the undercoats of paint prior to your dull coat wasn't cured could be a problem. Only you would know for sure. Other than that I would just make sure the bottle was well shaken.
The only way I speed up paint drying with acrylics is to make sure light coats are sprayed and sometimes I shoot straight air through my airbrush or sometimes a hair dryer.
