Has anyone had the black plastic on the rear fading to a crappy gray color? I have been careful not to get wax on them . Thanks

 

You can clean them then use Mother's Back to Black.

 

Mine is turning grey on the exhaust shroud areas. I think it has to do with the heat of the exhaust (Racingbeat). I haven't tried fixing it yet but i think i might try the Mother's Back to Black.

 

Have any of you guys tried the Mothers "back to black" ?

 

Use Maguiars NXT to prevent this from happening.

 

ive tried the back to black, for best results clean very well with a tiny bit of soap in a bucket of water then wash very well, wait till it is fully dry then apply the back to black...i usually go through it twice and it comes out very nice, it holds up pretty well for about 3 weeks till it starts to grey out a bit, i usually wash my car every 2 weeks with the water restrictions and detail it in between. btw it works well on the underside of the side view mirrors and also where the windshield wipers are...just try not to get it on the car it gets messy...

 

A simple search would have turned up this and a few others:
