Hey guys,
Searched around the forum, best results to fix faded trim. This thread
Faded window liner/skirts and Peanut butter not keen on it. I have my side quarter windows, targa roof trim faded marks on exterior. I have tried Meguiar's Plastic X, Meguiar's trim detailer, these do work but the exterior trim that has the grey faded marks; these products tint the grey. Does not darken enough to be "Black" with the other trim.
Chase_D tried yesterday something he has used on his trim but didn't work either (Attempted on targa trim) Personally I can spend up to 4 hours cleaning and still not be happy. This is one of those things that irritate me.

I was thinking "Mother's Naturally Black" but it will just have the same result as Maguire's I reckon.

Any suggestions? I have heard about a black dye that contains a chemical to it, never was told the name.
