Scratch-Off Acrylic Window Scratch Removal Kit is a precision surface restoration system for aircraft windshields, side windows and landing light lens covers. Developed for the Aerospace industry in 1994, Scratch-Off has been hard at work restoring optical clarity to aircraft windows and windshields. Damage to aircraft windows is more than a cosmetic challenge, it can compromise flight safety by limiting your ability to see traffic or even the destination airport. Throw in a little rain or window fog and visibility is often worse. Plexiglas aircraft windshields and windows are also subject to stains and etching from environmental pollution, acid rain, pitting from prop blast, and discoloration from sustained UV exposure. When turning, climbing or descending, the sun can hit the pilot at such as angle that every infraction, every defect, every scratch is amplified and glaring at them at eye level. These defects are distracting at best and can be a safety issue especially during dawn and dusk take-offs and landings.
