do you use a black toner like ppg 9700 and mix it with a clear?
if so what ratio do you use. i've been thinking of experimenting with that myself, but didn't wanna ruin headlights and tailights just to experiment.
Those were done just by mixing base and clear, tho not reccommended by ppg ive never had a problem with it. The next set i do im going to give it a shot using and intercoat mixer
