just a quick tip if it hasnt allready be posted on here.recently bought a older windshield for my boat and though it was in good condition it was a little cloudy .tried the usual suspectes with little sucess.so went to local auto parts store (canadian tire) and bought mothers plastic lens restorer.well about a hour later i have a crystal clear windshield with lots of restorer left over for headlights on a dozen vehicles or what ever.note this is a plexi-glass windshield and i havnt tried it on anything else other than my headlights which made a huge diff.the kit comes with a small powerball applicater you attach to your drill and some heavyduty pads which i did not use and the restorer.worked great with little effort.
