The molding (body colored black emerald like the rest of the car) has started to oxidize on each of my doors. Any thoughts on how to replace them or where I can find them to buy? The level of oxidization is too heavy to rub out.
Thanks!

 

If you mean the thin strip of moulding on the doors, you can order them from Courtesy Nissan. I think the prices for different positions vary, but last I checked the retail price for black emerald on the front driver side door is $96.84 and Courtesy sells it for $77.47 + shipping.

Th moulding comes painted, but removal and installation requires use of a heatgun. If you're good with a heat gun then it'd be a DIY otherwise you should get a body shop to do it.

BTW, the reason I looked into it is because the front driver side moulding started to fall off :P
