Amazing paint job! Just bought mine and had to resist going for the 'learning project custom' one too!
been looking deeperintothis sticky sitch. ouching and feeling my toys. Seems like the clearcoat i use only reacts to clear and trans vinyl, and newer clear vinyl at that. something dif about it. so rootbeer globby which is trans green had plenty of time to offgas so no probs at all with sticky or tackiness. And same with new fancy haircut which is on neon glow green. Weirdness, and the joy of chemicals.
