Now this is interesting to me, because the Deere enamel I have sprayed down here is by far and away thicker out of the can that either PPG or DuPont acrylic enamels. That's why I have had to go to thinner, multiple coats. If I back off on reducer, it just doesn't like to atomize as well. Maybe with my new gun it might make a difference. I have notciced that the JD fast dry is the thinnest, and then next comes Classic Green, and then the ag Green, which seems very thick ! I'm kind of old fashioned in that I use a viscosity cup to get relative readings to use to set up enamels that I don't often paint. The acryilics I can adjust with reducer volume and temperature, but the synthetics I can adjust by viscosity. I thought it might have something to do with higher temps when I paint, but that should make the paint pour faster, too. On the clearcoat over synthetic or alkyd's, make sure it is good and cured. I just painted over some that was a over a year old. Cleaned it up with 400 grit wet and sprayed on the clear. I've been told that unless it's very, very, cured, you might get some "separation anxiety". I just tried some clear on some wood that I have exposed to the weather. Kind of expensive varnish, but not if it lasts for 4 or 5 years. Frank
