The Sanding Process

Starting with the coarse 320 grit paper, sand in small sections of the headlight at a time. Using dry sanpaper, move in horzontal and vertical directions. Gradually move to finer grits from 320 to 600 up to 1000 grit. With the finer paper you will notice the surface get smoother and more clear. It important to remove all of orignal factory coating during the 320 grit step. Otherwise you will see the coating when applting the vapor sealant.
