I used a forever black kit on my Tacomas plastic fender flares and it looks like chit now. The forever black formed a paper thin layer of black **** over most of the fender and it sprayed off wiht a high pressure car wash but it did not really "dye" so to speak, it did leave a couple of patches that would not come off. Its a TERRIBLE product and it may have permanently damaged my plastic trim, is there anyway to get it off?
