I haven't personally dyed or sprayed any, but from everything I've heard, it looks great if done properly. Everyone I know agrees that the re-pops are JUNK...Stay away from them. I've always advised people needing E-body door panels to get a good used black set and use them black or re-color them. In your case you have a black set with good grain, albeit faded. Buy the SEM dye and re-use what you have. Save your money by not buying another set of panels...
