Diamond ProTech Diamond Glass Prep Reviews
Customer Reviews
My prep was brown in color I don't know if it has gone bad or a new formula but I was not impressed by it or the glass coating at all and I installed it last week!!!

Would they buy this item again? Yes
Cleans your glass very well. This is my go to glass cleaner. Removes oils and dirt to a squeaky clean glass before coating.
