    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.

    I reviewed this before but don't see my review on line yet? Anyway, got my Hydro Blue Sio2 Coating and am getting used to the Application Process. Have a 2018 FORD EDGE in Metallic Blue. I used about 1/2 the Bottle on my first Application and was kinda bummed out at how much I used. The stuff goes on to easy and comes off way to easy, Leaves the Vehicle Shiny and smooth everywhere, Chrome, Glass, Wheels, HeadLights, everywhere it looks Beautiful! I did ask Nick about my usage and he did reply that 5OZ should do the Edge. So, I purchased a Different Sprayer to use with my 2nd App, and... Wa La, much better atomization of the Product, and "LESS" Product Used!!! That said, At the Price Point, I would recommend getting a Professional Sprayer Like the one in the New Video with the Concentrate being shown.
