Hydro Graphene Ceramic Spray Coating (SiO2 Carbon Spray & Rinse Protectant), 22 fl. oz.

easy to use. cars stay cleaner a lot longer. slick surface on paint. used it on the rims also and brake dust doesn't stick near as much as before.

I've been a long-time user of 303 Touchless Sealant, which is a very similar Sio2 spray-on/rinse-off product. There are several similar products on the market. They are all extremely easy to use and provide fairly similar results. I'm a big fan of the speed and ease that these products provide. This McKees 37 product was the first of its kind that advertises the integration of graphene into the spray-on/rinse-off formula. I figured it was just a matter of time until graphene made its way into the market...so I decided to give this a try.I applied it on top of the already existing 303 Touchless Sealant coating...which was last applied about a month ago. The McKee's 37 product applied identically to the 303 product and all of the other similar products I have used. The end result for the McKee's was impressive. The hydrophobics, gloss, and shine are all a step above the 303 and the other products I've used. Really pleased. On the down side, the McKee's was not as slick as the 303. For that reason, I would say that McKee's is a superior coating (longevity pending, of course)...while the 303 is a superior drying aid.I'm undecided if I'll continue to use this product due to the cost...it is by far the most expensive spray-on/rinse-off product I have used, especially on a per-ounce basis. But, that being said...it's an impressive product.

I got this to layer over the dealer applied ceramic coating on a new EV6. Application was extremely easy. Wash, rinse, then panel-by-panel apply 3 - 4 sprays and *immediately* rinse. Work quickly -- hose in one hand, Hydro Graphene bottle in the other. You'll actually see some suds appear in the rinse water as it activates the Hydro Graphene. A little product goes a long way and water is your friend. Really flood the panel (and hit the surrounding panels in case of overspray) to get the product fully activated and distributed.Water sheets nicely off the treated panels and the depth of shine after drying is impressive. I can't yet assess the longevity, but the product is so easy to use that even if I have to reapply every few months, I'll be completely satisfied.

Works Amazing!

I used more than half a bottle on a Honda ridgeline truck. The end result was great, except on the windshield which seemed to leave a unwanted film. Using so much on one application seems expensive. Maybe I used too much.
