The clear plastic cover/shield over the "instrument panel" for the Yanmar (tach, warning lights, key switch, buzzer) on my 35.5 is weathered to the point of being almost opake. Not scratched, cracked, etc., just very "hazy". When wet with water on both sides from cleaning it looks almost new and clear. Isn't there a polymer conditioner, wax, cleaner that will fix it up for awhile? Seems I've read somewhere about a treatment for plastic windows in dodgers and/or bimini surrounds that might do the trick. Any experience with this out there?
