I was thinking of painting my 29 phaeton Balsam Green. I got a half pint of PPG Concept Balsam Green and it was very, very bright green. I also bought some Bonnie Gray and it should have a greenish tint to the gray. I am going to do a spray test of both colors to see how they look on a larger panel. BTW, when I bought the half pint of Bonnie Gray PPG Concept, it didn't look like the MAFCA Finishing Guide paint chip. It was a straight gray, no greenish tint to it. I then bought a 1/2 pt of Dupont ChromaPremier single stage acrylic urethane and it looked correct. I also had a problem last summer with PPG Concept Copra Drab. The PPG paint was a gray instead of a brown. I finally got some Dupont ChromaPremier Single stage paint and it was the correct color for Copra Drab. PPG doesn't seem to care about model A hobbiest. When I called them, they basically said "that is what we have". Kind of a take it or leave it attitude.
BTW, I have a couple of model A pictures of a phaeton painted Balsam Green. The phaeton doesn't look like Balsam Green, more like Valley or Vagabond Green. I like the Valley Green and Vagabond Green better, but they are not correct for 29 phaetons.
