Comparison
10H Ceramic Coating
vs
7H Ceramic Coating
The "H" rating system explained — and which level your car actually needs.
The 'H' rating you see in ceramic coating marketing references the pencil hardness scale — but the way it's used in detailing is largely marketing language. Here's the honest difference.
Side-by-side
Feature breakdown
| Feature | 10H Ceramic Coating | 7H Ceramic Coating |
|---|---|---|
| Surface hardness rating | ★10H (pencil hardness) | 7H |
| Lifespan (typical) | ★3–5 years | 1–2 years |
| UV protection | ★High | Medium |
| Hydrophobic effect | ★Strong, persistent | Strong initially, fades faster |
| Chemical resistance | ★High | Medium |
| Scratch resistance | ★Resists fine wash marring | Some marring resistance |
| Cost | $899+ | ★$300–$450 |
| Pro install includes paint correction + warranty | ★Yes | Rarely |
Our Take
The honest answer
10H ceramic is the right answer for any vehicle you plan to keep more than 2 years. The lifespan difference (5 years vs 1-2 years) means 10H costs less per year over time, even at a higher upfront price. 7H makes sense for short-term-ownership cars, lease vehicles you'll return in 2-3 years, or budget-constrained jobs. We use professional 10H exclusively because the math always favors it for owners.
Questions
Frequently asked
Is 10H ceramic actually 10H hardness?
+
On the pencil hardness scale, 10H is the top of the chart — harder than any standard 9H coating — that's technically possible for cured ceramic films. In real-world terms, 10H coatings resist fine wash-induced micro-marring much better than 7H. They're not bulletproof — neither rating prevents rock chips or curb scratches.
Why is 10H more expensive?
+
Two reasons: the formulation costs more (higher SiO2 content), and application requires more careful surface prep (paint correction included) since 10H locks in whatever's underneath for 5 years. Cheap labor + cheap product on damaged paint = a 5-year mistake.
Can I apply 10H ceramic myself?
+
You can buy the same product we use — but the bottle is only half the job. Results depend on machine paint correction first, IPA-prepped paint, a controlled environment, and precise leveling within minutes of application. A professional install includes full paint correction and is backed by a warranty; a DIY coat over swirled paint locks those swirls in for 5 years.
