McKee's 37 - Hydro Graphene Ceramic Coating | Easy Spray On Ceramic Coating for Cars | Extreme Shine, Hydrophobic Protection & UV Resistance (128 oz)

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.

Great product! Followed the instructions and ended up with a really great looking F150 with a fantastic looking shine.

for DIY detailing enthusiasts like myself, applying a traditional ceramics or graphene coatings in a glass jar is not my thing. Spray-on ceramics and graphene coatings is more my speed for average DIY'ers. This McKee's makes it even easier. Wash car, don't both drying and just spray this on and rinse off - that's it. After the rinse off, I'll use a wet wax as a drying aid but really not needed because the slickness and water beading (even without a drying aid) makes it so easy to dry as not much water really sits on the car idly. I bought 2 gallons of this stuff just to help family members coat their cars. It's like a family get-together event and it's super easy. This stuff amazes me, the rinse-on and rinse-off just makes it easy and enjoyable. Whether it lasts long or not, doesn't matter because you'd just re-apply by rinse-on and rinse-off method.

The hydrophobic aspect is really great! It obviously very easy to use as well. I cant really speak to the longevity of the wax yet. Its very pricey for what you get. Not sure yet if its really much better than the regular hydroblue which is much much cheaper.

The product went on easily as advertised, but the water didn't roll off like in the video. It beaded up and I now have tons of water spots and it looks dirtier that before I sprayed it.

I've been using McKee's for some time. The products are consistently great.

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.

if it seems too good to be true, it is. The idea that you can just spray it on, hose it off, and get a fantastic, long lasting shine seems almost impossible. It is! I read the directions and watched the application videos. I followed them to the letter. It does create a really nice shine, however, there are serious problems. First it leaves gunk behind, you can see it when a light hits it a little bit off at an angle. Looks like it followed the water pattern as water flowed off the car. It’s particularly problematic on windows. You do not want this on your glass, but there’s no way to avoid it. Buffing, and buffing, and buffing with clean microfiber helps, but does not completely remove the patterns. It better wash off over time. Definitely not a repeat for this product.
