Has anyone had any problems with the material inside the rear wheel wells? Inside front wheels is standard plastic - seems pretty durable. Rear wheel wells have some other type of material - almost like acoustic insulation or something. Doesn't seem very robust. Mine is fine but also new. Any experience with bad weather driving (like getting a lot of sludge, road salt, etc.) and how does it look when cleaned up?

This was discussed many moons ago, and it was determined that this material has been used on other vehicles for quite some time now, and appears to last just fine. Try the search function if you need more detail. :)

thanks, I did but probably just not the right word combo.
