If you're gonna do a plexiglass overlay, you can just use the black, vinyl shelf paper at Lowe's. The last multi I built utilized this $5 method and looked simple but effective. The roll is about 18" wide and like 15 feet long. So, yes, you'll have some extra.
Without the plexiglass cover though, it'll get trashed.
I covered my cabinet in HAPP's black pica vinyl, and I also used it for the control panel. But I did put a piece of plexiglass over it. It's not flashy, but it looks nice.
