Wow! Just wow! Received your product last week and used it today on the windows of our Princess F55. We took her from Naples to Maine in June and the hard water stains were impossible to get off the glass. Your product was amazing. We had tried a number of products - mostly non-marine - and yours is the first that worked; with ease. Thanks for your product doing what you said it was going to do!
Incredible performance—boat looks brand new. Loved the sale price too.
Impressed with the visibility after just one use. Great price for the quality.
