I think I see the issue. With OL, I suggest you only strip-fix the top 1/4-1/3 and then compound and coat the entire lens. Saves a ton of time and effort that isn't required. On many cars, that means no more heavy grits because it's not needed to fix what's already gone. Often all you need is 1500 give or take, blended into the good coating. That is the equalizer, and is what I meant by doing some of the easy cars with optilens. They aren't so easy if you sand down the entire lens. :buffing:
