Keep the number plate where it should be, just shorten the recess if you have a short plate, that's what I'm doing when my car goes into the bodyshop later this month, along with getting the grooves filled and smoothed. There's no easy way of getting the indicators into the headlights so I'm not going to bother smoothing over the fog/indicator areas, plus if you ever break down, I'm guessing you won't have access to your tow eye.
