Hey guys.

I washed clayed and waxed with meguires products the other day and today i took out the car and i noticed the black shiney part of the z that seperates the front window from the little back corner window was all swirled and marked up. That particular part on the z i can already tell is going to cause problems. it looks soo delicate.

Is there a recommended product you might suggest that would work on getting that piece looking like new again?

Thanks
