Understanding 10H Hardness in Ceramic Coatings

What Does 10H Hardness Actually Mean for Your Car's Protection? 🚗

The 10H hardness rating you see on ceramic coatings isn't just marketing jargon, it's a real measurement using the pencil hardness scale. When a coating achieves 10H, it means it can resist scratching from even the hardest graphite pencil (9H) whilst providing superior protection against daily wear. This matters because harder coatings better resist minor scratches from washing, road debris, and environmental contaminants that would otherwise damage your paintwork permanently.

Many car enthusiasts get confused about hardness ratings, thinking higher numbers automatically mean better protection. The truth is more nuanced. A genuine 10H ceramic coating like our NL272 creates a sacrificial layer that absorbs damage instead of your paint, but it won't stop major impacts or deep scratches. What it will do is make your classic or modern vehicle easier to clean, more resistant to water spots, and maintain that showroom finish for years rather than months. What's been your biggest challenge in keeping your vehicle's paintwork pristine?
