McKee's 37Hydro Graphene Ceramic Coating | Easy Spray On Ceramic Coating for Cars | Extreme Shine, Hydrophobic Protection & UV Resistance (22 oz)

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.

Follow the instructions it's super easy water hose in one hand and spray in the other dry it and done!

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.

Pretty new to Mckee’s 37 products, all great, all 5 stars and this one is no exception. I just follow the simple instructions, wash my vehicle and while still wet spray a few squirts on each panel, not the whole vehicle, then rinse thoroughly and dry to an amazing hydrophobic finish. Sure it’s a little expensive, but according to Mckee’s 37 this spray coating will last for 3 to 6 months. The reason I’m giving Amazon one star is because like many other liquid products that I order from Amazon, this one came leaking because of the as per usual sub bar packaging procedures from Amazon. Thankfully it didn’t leak too much so there was no need to return the 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.

As a long time user of McKee’s ceramic products, I had high hopes for this graphene tire shine. It is best applied with a sponge applicator, and gives nice shine when fresh and does not sling as stated when given an hour or so to dry. The problem is the shine just doesn’t last much longer than cheaper regular name brand tire shines. This stuff maybe lasts a week or 2 at most if it doesn’t rain. So at $40 for this bottle, I could buy 5-6 bottles of cheap stuff and ultimately get more tire shine.

Works great!

Easy to apply, just wash the car and spray on wet vehicle in sections and the rinse. I immediately saw beading of water and after drying the car it had a smooth finish. I went through half a bottle for the entire car. It's a 2018 that's been parked outside it's entire life in SoCal. I'll update the review in two to three weeks when I wash the car again.
