I really didn't need to fix anything track wear wise for the night version of Daytona. It wears in VERY GRADUALLY and is very discrete to notice even 15-20 laps into a run. With a big field though I anticipate it will darken a bit more but the terrain is so dark to begin with that you only notice it slightly in the light.
I did remove the wear in the grid since that was still visible.
