When we paint plastic or vinyl with SEM, or Colorbond Spray paint, which is made for plastic or vinyl, we clean it real good, then wipe it with lacquer thinner. Lacquer thinner, not only sucks the oil out of it, but it actually softens plastic a little allowing the paint to adhere to it. The lacquer thinner will make old black vinyl turn whitish until you spray it. This occurs because the lacquer litterally sucks out all the oil in the vinyl. On the other hand, if, lets say a dash has ever had armor all on it, the paint will fish eye terribly. So I'm faced with the decision , weather to armor all them and keep armor all on them all the time or paint them and possibly devaluing the kit.
I'm very curious how this would work on the Black Panthers. Can't wait to see the results of all your testing, since you're a professional "car guy". On my own Black Panthers, I've always just used the Armor-All Protectant Wipes in the dispensors.
