Wheel arch (band?)

[AlanD]

Am a new 350z owner. Have beginnings of bubbling in nearside rear, and more established bubbling at from nearside front . Took rear wheels off today and noticed that grit etc was being held under the band, which had lifted. The offside band was still fully attached but I could see the beginnings of issue. 
Not sure what the band is for other than to smooth out a thin edge to help prevent rust, though it is actually now causing the problem. Was contemplating removing it, in order that I can ensure full coverage with Kurust and then add either lanoguard type product of stone chip.

Have read a previous post that, unlike the front, there is not a complete plastic cover for the rear, though there is a gap between the arch and the cover is causing the issue at the front.

the attached photo is before I ran a braddle fully underneath and realised it was a band which was loose.

thanks in advance for responses.

Is it a strip to stop wheel liner squeaks against the body? 

 

In any case, you can remove it, clean/paint/seal the wing, then glue it back right?

I thought it might be that Keith, but there is no liner on rear wheel arches. 

Perhaps someone will jump in and correct me.
Hopefully, have a dry weekend soon so can have a proper look and see if there is anywhere obvious where a liner, if it should be there, would attach.

I’d quite like to remove entirely but experience has taught me that everything is there for a reason and normally I just haven’t figured out what it is.

There are no arch liners on the rear, only the front.
