When I clean up the cladding I usually spray a bunch of tire shine all up in and around the wheel wells too. It has a way of making the vehicle look new. The cladding looks much better now but the wheel wells are still nasty
Just a tip, not knockin on you at all
This is what I use for the cladding and then I just use what ever tire shine I get for the wheel wells (two different products).
