    Hydro Blue is simply awesome!

    I've tried it on all three of my vehicles. They are different ages and range in paint condition. They all water bead like no other product I've tried.

    Great Stuff

    I purchased the electric air dryer for the car at was not impressed with how it worked absence a good coat of wax. When I called to return the item, I was advised I could get a refund with no problem but I was asked to try a free sample of the Hydro Blue. Upon receiving I was shocked at how easy and how well it worked. Great product for in between waxing especially for the rainy South Florida climate. Just ordered my large refill kit. Will keep using this product. Highly recommended.
