Have tried various products and home brews to remove the layers of water spots (covered every inch) on the windshield of our 15+ yr old boat for years with zero luck. Saw this product recommended by Capt Dorian Rogers in another thread and gave it a shot.

Incredible results - the water spots are basically gone and glass looks like new. Must use a buffer for it to really work, and depending on severity of spots it may take 2-3 applications, but it works.

Amazing to be able to look through the windshield with no spots and your eyes not trying to focus on those vs what's ahead of you.

Thanks for the recommendation and thanks Aquatech- product was relatively inexpensive and arrived within a couple of days.
