Quoted from Rondogg:What about your thoughts for a partial clearcoat? The area would really only be about 4"x8"...
It's tough to do, but I guess it's possible.
Try to map out where the edges of the new clear meet the old, and make sure those areas are places that will get no (or very little) ball travel.
Ending in protected areas like under plastics or between lanes would work.
