Bought a bottle of Cerakote Tire Coating. I shook the bottle for a minute. There was some gunk up at the top of the bottle. I think it mixed back up or settled to the bottom. My issue was that the sprayer wouldn't work. I ended up dumping it on the applicator and working it into the tire. Overall look is nice. Looks similar to Adams Graphene tire dressing, maybe a bit more matte looking. Other than the sprayer, I think it's a good product. Durability is to be determined.
