I dyed a black dash pad red in my 67 Barracuda almost 40 years ago , and it is still beautiful ! I used all ditzier prep material and I am not sure if the dye was Ditzler or Sem at that time , but I have used SEM on other things in more recent times . If you do proper prep , the dye will work well ! Kool
