Yes, the carpet will tuck into the aluminum side trim. That trim is anodized but anodize is a very hard material. You can get aggressive with it if you have to. I have had it bad enough that I had to use 0000 steel wool on it. I even had to do that to a set of NOS grills. I am actually not sure if polishing it will really help much other than maybe sealing it to keep moisture from getting under it and turning it cloudy.
