I have a 75 and the glass is scratched on the outside. I can still see my fish, but it is noticeable and just looks bad. Does anybody have a trick to hide scratches on glass. When I was younger I was a deck hang on an offshore crew boat. We ran crew to offshore platforms when the weather was too bad for helicopters to fly. Anyway.... the windows were plexiglass and we're scratched. I would put furniture polish on them to fill the scratches, but it did not last long. Any way to do something permanent?
