I did something similar a few years back. I went to a rice burner store and picked up a sheet of carbon fiber look sticker. It is a big sheet the stuff for like $5 bucks.
I removed the plexiglass/bezel piece from the dash, took a Dremel cutting tool and carefully cut the tabs that joined the plexiglass and bezel together. Next I took the bezel and secured it on the "carbon fiber look" with some tape so it didn't move around. I then took an exacto knife and carefully cut the shape of the bezel. This can be frustrating if you don't take your time and make accurate cuts. Next remove a small portion of the backing so the stickiness is exposed, place the cut sheet into the bezel. Tip: cleaning the surface with alcohol makes the bond much better. Now you can begin to cut the holes in the sheet that match the bezel. Once the holes are cut now there is just some minor smoothing to make the piece look natural, and clean. Super glue, hot glue the plexiglass to the bezel and reinstall. Tip:I found that the super glue will leave a residue behind as it cures, so if you don't let it cure completely before reinstalling you may have to pull it back apart to wipe the white residue.
