I used black Formica/Aborite. I made a template of the panel with plywood, clamped the laminate to the plywood and used a router with a laminate bit with an edge guide. Because I needed black, I used the Formica as is.
That's right! If you have a router and a ball bearing laminate bit, it makes the work slick and quick. Just be certain to use the straight bit and not the edge bit...
