I recently have takern the front part of my Triple M tray off to turn into a flatbed. Unfortunately in doing so I have exposed quite abit of unprotected aluminum. I was wondering If someone could point me in the right direction to clean this up and make it look abit better.

I went to a bodyworks place and they suggested a "Rear Combins Board"

I have circled in red where I am talking about - and done some close up shots.

This is my first post and any help would be greatly appreciated. I hope to get this edge fixed so I can put down the Marine carpet down this weekend
