Does Meguiar's have any type of anti-fogging product for interior glass. Here in the tropics (Barbados, Caribbean) the days can be hot and i use the a/c alot. The problem comes on rainy nights, with the sudden cooling of the day and the car being closed, the windshield fogs up in no time and trying to clear it using the a/c does'nt seem to help alot. It seems as though glass both absorbs and retains heat......so with the sudden cooling of nightime rain fogging occurs. Any tips on this??
