(if the pics don't come through on here....goto the Saihavasu Message board at: _http://www.quicktopic.com/40/H/LSmQsY3ZHAv_ (http://www.quicktopic.com/40/H/LSmQsY3ZHAv) "Dauntless" has some pretty old Grey Marine polycarbonate opening ports in her. I love them as we live in a hot location and opening all 6 of them is fantastic ventilation. Over the last 15 or so years (they were in there before we purchased her) the sun has had her way with them, clouding the lenses until they have become totally opaque. Nothing would clear them up, even temporarily. I recently used a 3M headlight restoration kit on my truck. I was so impressed with it I figured "what the heck" and gave it a try on one of the ports. Keep in mind that replacing the lenses woud cost hundreds of dollars and removal of the ports. In 20 minutes with the leftovers from the $20 kit I used to polish the headlights...the lense went from this: to this: (and the picture does not do it justice) I figure since I already did 2 headlights that I should be able to get 3 ports done per kit. Total cost $40 (less than $7 per port) and about 20-30 minutes time per lens. TOTALLY worth it!! I have tried other headlight restoration kits that didn't work for crud. This kit is fantastic!!!! I figured I would share this in the hope that helps out someone who has had the same thing happen to their ports.
