The use of 'dyeing' is a misnomer when talking about certain plastic parts such as the door panels. You can't dye it, you can only paint it, like with the SEM paints. Even their vinyl 'dye' doesn't actually dye vinyl. It paints it but it sticks really really well, like it was dyed.Plastic that you 'can' die is nylon. I've taken white nylon plastic pieces and using clothing die in a saucepan of hot water, dyed them black. Nylon will absorb the die and truly change it's color all the way through.
