Any tips for the wheel wells on the 2009 G37 coupe? They appear to be some sort of really rough, soft, composite material. Scrubbing them with a wheel brush and some APC doesn't really seem to do anything. I have never seen this type of material in a wheel well, it is closer to fabric than plastic/rubber like most cars have. Once cleaned, any recommendation for dressing?

 

are you talking about the rears?

Theres carpet lining inside the wheel wells of the rear.

 

I use this stuff on my wheel wells and they come out looking amazing:

Literally from road salt white to black in a matter of seconds!

 

My typical process for washing wheelwells is the following;

* Thoroughly hose down the wheel wells with water to remove dirt, mud, etc
* Clean wheelwells with simple green APC and a wheelwell brush (without using too much pressure.).
* Protect with 303 Aerospace
