Charging the buffing wheel

Once the shield is cut out, you will need to do something about the rough edges. You can simply sand them with "Wet-Dry" black sandpaper in 200-600 grit or if you want a "factory" edge, you will want to buff the edge on a soft musslin wheel using a fine buffing compound. Don't stay in any spot too long or the lexan will melt. Keep it moving.
