I'm not sure if my side skirt (the black/grey panels on the doors) are supposed to be grey. Whenever I was the car, there are left over black, black areas and the rest looks faded and grey. Any good products to use to get it's nice color back?

They were grey on my TR.
Are you talking about the kick panels or the panels on the actual door?
The door panels were grey and the kick panels were blue (i had blue interior, pretty sure the grey interior had darkish grey kick panels).

Mines grey.. when i wash it they go black and can stay black for awhile but always fade back to grey...

If you talking bout those nice grey things on ya door that are the same plastc as your front and rear bumpers (assuming the not coloured) then juz give em a good wipe down with amor all gives it back most of the colour it should have.

there is a product that makes faded black go back to black, but i think it is for all the rubbers around the windows, not to sure aout the sides of the car. Anyways its is should be painted so match the car.:D

True, but it leaves everything greasy al hell.

Best bang for buck product would have to be; Mothers Back-to-Black. Look it up...

similar sort of thing ... Meguairs Trim Detailer. Found it at Repco
