McKee's 37 Graphene Ceramic Coating is a semi-permanent paint protectant built on graphene-oxide ceramic resins. It is marketed for paint, wheels, chrome and glass, with a claimed lifespan of up to five years and a revised six-hour cure. The pitch is a no-compromise mix of easy application, durability and gloss, which is where most consumer coatings force a trade-off. It suits DIY detailers who want a long-lasting coating without a professional install, though a coating at this level still demands careful prep and a controlled cure.

Rated 4.7 out of 5 across 66 ratings, buyers largely report easy application and strong gloss. Few detailed complaints surface in the ratings, so long-term durability is the open question.
McKee's 37 Graphene Ceramic Coating is a semi-permanent paint protection coating made from a blend of graphene-oxide ceramic resins. It can be used on paint, wheels, chrome and glass. It can also be used on boats, planes, motorhomes and RVs.
The coating has a 10H rating on the pencil hardness scale. It forms a hard layer that helps reduce scratches and swirl marks compared with bare clear coat. It produces lasting water beading and protection that lasts upwards of 5 years. Application is similar to applying a liquid wax or paint sealant, and it comes in a glass container.
Prepare the surface first. Decontaminate the vehicle chemically and mechanically, polish it, then wipe it down with a coating prep spray. Apply the coating to one panel at a time with a coating applicator, going side-to-side and then up-and-down. Wipe off the excess with a short-nap microfiber towel, using short, firm strokes and flipping the towel often. Keep the vehicle away from moisture for 6 hours.
