If you've been in the detailing industry for more than a season, you've seen the numbers. 3-year coating. 5-year coating. 7-year. 9-year. There's a company in Japan right now selling SiO2 chemistry for approximately $20 a gallon. Professional detailers are buying it and running 10-year coating ads.
I want to talk about what that actually means — not for us, but for you.
Where Year Claims Come From
There is no independent test body that certifies coating longevity. No ISO standard. No third-party verification process. No lab on earth can tell you a coating will last exactly 5 years because the variables that determine longevity are entirely outside the manufacturer's control the moment that bottle leaves our warehouse.
Year numbers exist because they sell. A detailer can put "5-year ceramic coating" on a rate card and charge accordingly. The coating company gets to say their product justifies a premium. Everyone wins — until the customer comes back in two years, angry, and it's your name on the invoice. Not ours.
That's the part of this conversation most manufacturers don't want to have.
The Variables They're Not Telling You About
Coating longevity is a function of at least five independent variables, none of which a manufacturer controls after the sale:
01 Surface Preparation
A coating applied over contamination, oils, or an improperly decontaminated surface will fail early. Not because the chemistry is weak — because there was nothing clean to bond to. The covalent bond PSZ chemistry forms is permanent when it has a proper surface. When it doesn't, you're coating the contamination, not the substrate.
02 Application Environment
Temperature, humidity, airflow, and ambient cure conditions all affect how PSZ crosslinks during the initial cure window. A coating applied in a cold, humid garage in November in the Pacific Northwest is not performing the same chemistry as one applied in a controlled 70°F environment. Both can work. Neither will match a lab condition rating.
03 Wash Chemistry
This is where most coatings fail — not from age, but from chemistry. Alkaline detergents, dish soaps, and harsh wash products degrade PSZ surface performance over time. The covalent bond to the substrate holds. The hydrophobic surface layer erodes.
A garage-kept car washed after every outing with a neutral pH soap will significantly outlast the same vehicle run through an automatic car wash weekly. Same coating. Completely different outcome.
04 Environmental Exposure
A boat moored full-time in a saltwater marina is operating in one of the harshest chemical environments on the planet — UV, salt, biological fouling, constant moisture. Compare that to a garaged weekend vehicle. These are not the same application.
Any manufacturer giving you the same year rating for both isn't being honest with you.
05 Application Technique
Technique matters. Application differences directly affect performance. Two thin coats leveled sooner can outperform one heavy coat. The coating may not fail — but the result won't be optimal. That's the kind of thing a manufacturer who actually uses his own product tells you. Most won't.
The Real Cost of a Dishonest Claim
A detailer buys low-cost coating, runs long-term claims, and builds a business on a number that has no foundation. For a season, maybe two, it works. Then customers come back when performance drops.
Whose reputation takes the hit? Not the manufacturer. The detailer. The person who looked a customer in the eye and made a promise they couldn't keep because they trusted a number someone else invented.
Your reputation is the only thing in this industry that compounds over time. A customer who trusts you brings their next vehicle, their spouse's car, their boat. A customer who feels misled tells everyone they know. The math on that is brutal — and it plays out over years.
What We Actually Commit To
We manufacture professional-grade polysilazane coatings. We own the lab, the formulas, the bottling line, and the warehouse. We don't make consumer products. Every formula we build is designed for professional application, maximum durability, and ease of leveling — because our customers are professionals who are putting their name on the work.
Here's what we're willing to say in writing:
Dragon Pro — Marine
Marine environments vary too widely for a single number. Our guarantee on any marine application is 18 months — no questions asked, we replace it.
What detailers are actually seeing in the field:
- Saltwater marina, full-time exposure: 3 to 4 years with proper maintenance and neutral pH wash chemistry
- Boathouse or covered storage: 5 years
- Trailered, weekend use, garage kept: 6 to 7 years
AutoCoat — Automotive
5 years on automotive with proper care and neutral pH wash chemistry.
These numbers assume proper prep, reasonable application conditions, and correct maintenance. If any variable is off, the number changes — for any coating, from any manufacturer, at any price point.
And if there is ever a problem — with our formula, with a batch, with a result you can't explain — we replace the product. No questions asked. We're not going anywhere, and we're not hiding behind a number we invented.
The Question Behind the Question
When a customer asks "how long does it last," what they're really asking is: can I trust you?
The honest answer isn't a year rating. It's an education. The coating is the beginning of the process, not the end. Wash chemistry matters. Maintenance with a product like ReVive extends the life of their investment. The variables the customer controls are the ones that actually determine the outcome.
That conversation, at drop-off, is part of the professional service. It sets expectations correctly, protects your reputation, and creates a customer who understands what they bought — and comes back.
We're here to be that partner. The one that's honest about what the chemistry can and can't do, and stands behind it when something goes wrong.
That's the only claim worth making.
