It does not stop scratches
9H is a pencil-hardness rating for the coating itself, not armour for your car. Trolleys, keys, stone chips and automatic wash brushes will all still mark it. Anyone who says otherwise is selling, not explaining.
This is the most oversold product in the detailing industry. Below is what a 9H coating actually does, what it definitively does not do, and the specific situations where we will tell you to save your money.
Not a wax, not a sealant, not a spray-on. It is a liquid polymer that chemically bonds to the paint and cures into a semi-permanent layer roughly two microns thick. Wax sits on top for eight weeks and washes away. This does not.
If a detailer claims any of the below, walk away. These are the three things that generate almost every disappointed coating customer.

Coating is clear. Every swirl, every scratch, every bit of haze underneath gets sealed in and magnified for five years. That is exactly why correction is built into the price rather than sold as an upsell.
You still wash it, just far less often and far more easily. Go back to the tunnel and the brushes will grind the coating down inside a year — and the warranty does not cover that.
In these cases a Full Detail plus paint correction gets you 85% of the look for a third of the price. We will tell you this on the phone before you book.
Over five years the coating costs about $258 a year. Waxing properly twice a year at $180 a time costs $360. The coating is cheaper and it works better.
Roughly 80% of the price is the preparation. The coating itself takes about ninety minutes to lay down — everything before it is what determines whether it lasts five years or eighteen months.
Snow foam, two-bucket wash, iron fallout remover, tar removal, then clay bar across every panel. Anything left on the paint gets sealed under the coating permanently.
Paint depth gauge on every panel before a machine touches it — you cannot put clear coat back. Then a full machine polish to remove the defects that would otherwise be locked in.
An IPA wipe-down removes every trace of polishing oil so the coating can bond to bare clear coat. Then the coating goes on panel by panel and is levelled within its flash window.
Garage overnight, dry, no rain. We come back to inspect in daylight, hand over the aftercare kit, and book your free twelve-month inspection before we leave.

Most shops quote coating and then add correction once they have seen the car. Ours is one number because you cannot do one properly without the other.
Works out at about $258 a year over the warranty period.
Book a coatingTwo-stage correction, for paint that needs more than a single pass, is quoted after inspection — usually $250 to $400 on top.
Worth it if you are keeping the car three years or more, you park outside, and you hand wash or use touchless. Not worth it if you are selling within a year, the paint needs bodywork first, or you will keep going through automatic brush washes.
We turn down roughly one coating enquiry in five for exactly these reasons. It is not a hard sell — an unhappy coating customer costs us more than the booking is worth.
No. 9H refers to the hardness of the coating itself, not your car's resistance to damage. It resists light marring and chemical etching. It will not stop a stone chip, a trolley, a key, or a tunnel wash brush. Any detailer who tells you it will is overselling and you should be sceptical about everything else they say.
For the coating stage, yes — it has to go on in a covered, dust-controlled space and then stay dry overnight while it cures. The correction on day one can happen in the driveway. About nine in ten of our coatings are applied in the customer's own garage.
No garage? We can arrange indoor space at a partner unit in Westbury for an extra $120 to cover the day rate.
Two buckets, pH-neutral shampoo, a clean microfiber mitt, top to bottom, dry with a plush towel. Roughly every two to three weeks. Touchless automatic washes are acceptable when you are short on time. Brush tunnels are the one thing that will genuinely destroy it — and using them voids the warranty.
Coating failure — delamination, premature breakdown, and loss of hydrophobic performance. It requires the annual inspection, which is free and takes twenty minutes. It excludes stone chips, accident damage, and anything caused by brush car washes. The full two-page document is handed to you at completion, and we will email it in advance if you want to read it before booking.
Send a couple of photos and tell us how long you are keeping it. If a Full Detail and correction is the better spend, that is what we will tell you — it happens roughly once a week.
