    what does 9H mean in relation to coating

    I'm thinking it's meant to designate hardness. Diamond being a hardness of 10.

    It means squat. Meaning don’t buy into the marketing of coating hardness. They can still swirl and scratch. They do help with wash induced marring that may occur.

    Re: what does 9H mean in relation to coating

    IMHO, it's just a silly marketing ploy. I haven't noticed coatings being any less resistant to swirling or light scratches than the original clearcoat that comes with a car from the factory.

    Re: what does 9H mean in relation to coating

    It refers to the hardness of pencil lead with 9B as the softest and 9H being the hardest. A standard number 2 pencil that we all grew up with is actually an HB lead which is close to the middle of the scale. The 9H hardness test measures the hardness of a clear surface coating by its ability to resist scratching with a 9H pencil.
