Hey bud.. Yes this would be beneficial if the clear is peeling. However you would prolly want to use 600 grit then go to 800, 1000, 1500, then 2000. The 600 will get rid of the clear coat. YOU WANT TO SAND ALL THE CLEAR COAT OFF! That important. Cant leave some on and take off the rest. Goodluck. Just ask if you have anymore questions.
