What is suggestyed to restore the black plastic over the rear side windows on my 03 Xtreme. Right now they have a light gray look to them.

The best way would be to remove them and paint them. I used spray on bedliner on mine but that's because I have bedliner all over my truck already. For yours I would spend a little extra and have shop paint them body color to give it that little extra touch! If that's not in the budget then some nice gloss black from a rattle can will give nice results as well

How do you remove those? I too need to redo mine

take the door panels off, the side mirrors are held in by three screws.. and as for shinning them try back to black by mothers, it doesnt last forever which sucks but i usually do it every time i wash the truck

There's that product out there called whipe new. Works pretty decently (IMO) almost seems like a clear nail polish or something, and it stinks until it dries! If u use it I really recommend using in a well vented area. My garage smelled for a week or so. And DO NOT let it get on paint or windows. But like I said in my opinion it works
