Review on California Gold Water Spot Remover for Glass - 12 oz. by Mothers 06712 by Ken Coste

If you really want this product to work 100%, you first need the right polishing machine. If you use it with your hands on a towel, none of the many water stains will work as the constant acid rain has left the stains on it for months or years. My wife's car had a lot of acid rain stains. on its windshield, visibility when driving in the rain is almost nil. After applying this product to the polisher for 3 minutes at setting 5, I saw the windshield began to shine and was 100% smooth when I wiped it clean. OK. TRUST ME, THIS PRODUCT WILL WORK IF YOU HAVE A POLISHING MACHINE. Tips: Work with a small amount of buffing at a time for at least 3-4 minutes. Hand polishing is not possible!
