Clear or Smoked plexiglas?
I used a product, of course it's greatest characteristic is it's forgettable name, called something like Clear-Vue I think. I used it on the clear ports on my '76 and they came right back to clear.It's a two-part product, the cleaner and then the sealer/protector. You rub the cleaner on, the more liberal you are with it the faster the job goes, and then wipe on the sealer.I got it at Boat US, they don't have it in their catalog, it's sold on a blister card and the bottles themselves are about 3 ounces or so, about 3 inches tall and 1.5 inches wide. The instructions call for clean terry towel, but I discovered that paper towels work just as well.I won't be back to the boat until early next week, if you want, I'll get the name of it then.I've attached a before and after picture.
