I have a tinted, polycarbonate windshield on my 1996 Moomba ski boat that is so foggy that you can't even see through it. It is structurally perfect and doesn't have a single scratch in it. I am assuming this is oxidation but I'm no expert. Is there a product that can be used to restore this? Replacing the windshield is crazy expensive and that's if you can even find one.
