My 70 has (supposedly) factory gray interior, at least the seats are gray, but the guy I bought the car from gave it to his brother to "fix it up" as a race car....so what's the first thing he does? ......paints all the hard plastic interior pieces and door panels (including cloth inserts) with rattle-can black interior paint. Painted the dash (chrome knobs & all).....everything but the seats. Anyways, I'm wanting to switch some of the interior on my 69.5 from blue to gray, and would like to use most of the "hard" parts from the 70's interior (would rather use originally gray parts than painting the blue pieces gray)......if I can find a way to get the black paint off the parts without damaging the original color and finish underneath. Was just worried that thinner and other harsh paint removing solvents would harm the hard plastic parts. Anyone got any tips?
