Suggestions on where to purchase a small piece of black trailer door skin for a cargo trailer door?

Black countertop laminate is available in different gloss levels. Thickness is 0.035, stiff, flat, and no curling. Home Depot has it, but would most likely have to be ordered.

If I was doing this project on a budget, I would buy a sheet of marked down, damaged laminate and a spray can of Rustoleum Pro Series/High Performance spray paint - stuff lays out amazing.

The rolled plastic sheet worked. What I found nice was how easy it is to trim with a razor blade.

Now to find the trim piece for the door that provides the transition between the black and the silver.
