I got some scratches in my canopy when putting my RV together. Got the Micro Mesh kit and it came out perfect. But it was hours of work, as the area just gets bigger and bigger as you go finer on the abrasive. And it is important to not try to go small but instead feather it out (especially if it's in the windscreen), so you don't get a distorted area.
Bottom line, I'd think hard about whether you can live with before attacking it with the abrasives.
