Crystal Serum Ultra

Gtechniq Crystal Serum Ultra: What We Use Now

Crystal Serum Ultra is Gtechniq’s flagship ceramic, a dual layer coating that pairs a hard 10h top layer with a softer 7h base, and Gtechniq only sells it to accredited workshops. Liquid R no longer applies it. For cars being kept long term we now use Envoke ProCoat+ 7 Year Graphene Coating in Packs 1 to 4 of our new car protection packages, and Gtechniq Crystal Serum Light stays in Pack Essential. Call 1800 985 880 or text 0483 930 888 to book your car in. Separate guides cover Tesla and EV protection.

Dual Layer Chemistry

Ultra lays down two layers in one application: a softer 7h base layer underneath and a hard 10h top layer that takes the abrasion. Gtechniq rates the pairing as more swirl resistant than a regular 9h coating, and that combination is why it outlasts single layer consumer ceramics. Separate guides cover the Tesla Model S and supercar protection.

Professional Hands Only

Gtechniq restricts Ultra to accredited detailers, and Envoke does the same with ProCoat+: it is supplied only to established professional detailers Envoke has approved, and Liquid R is on its list of ProCoat+ installers. Mistakes are expensive either way, because once cured a bad application can only come off with machine polishing. There are dedicated guides for the Porsche 911 and Ferrari.

The Warranty Paperwork

Ultra carries a nine year Gtechniq guarantee through accredited installers. ProCoat+ comes with Envoke’s own customer warranty and care guide, and Crystal Serum Light carries a five year Gtechniq guarantee. Whichever coating goes on, the care routine from our Mitcham workshop is what keeps it performing. You will find the same detail for the BMW M cars and Mercedes.

The Prep Underneath

Before coating we foam wash, strip iron and tar, clay the paint and machine polish it under inspection lights. Any coating locks in whatever it covers, defects included, which is why our detailing stages are not optional extras here.

What It Costs

Our ceramic pricing starts at $980 including single stage correction. ProCoat+ comes in Packs 1 to 4 of our new car packages from $1390, and outside the packages we quote it per car, since paint condition and size drive the hours. Full options are on the ceramic coating page.

Coating Over Film

Cars wearing paint protection film can be coated over the film, so filmed and painted panels bead and wash identically. Film stops the stones, the coating keeps everything slick and chemical resistant.

ProCoat+ Or Serum Light

Honest answer: Crystal Serum Light does most of the job for most cars, with a five year guarantee, and it is the coating in Pack Essential. ProCoat+ is the step up in Packs 1 to 4 for owners keeping the car longer. Keeping the car past five years is the deciding question.

Living With The Coating

Two bucket wash, pH neutral shampoo, no brush car washes and dry with a towel rather than the wind. Water spots wipe off a coated car easily if you get to them. The routine is short and it is all written up on our aftercare page.

Booking a Coating

We coat inside the Cook Road workshop under controlled conditions and keep the car indoors while the coating cures. Book a few days ahead, drop off in the morning and the station is a five minute walk if you are heading to work. The product detail sits on prestige detailing.

Common Questions

Frequently asked questions

Straight answers before you book. Anything else, call 1800 985 880.

What do 10h and 7h actually mean?

They are pencil hardness ratings. Ultra cures to a hard 10h top layer over a softer 7h base, and the top layer is harder than factory clear coat. It means wash swirls struggle to mark it. It does not mean stone chips bounce off, that job belongs to film.

Do you still apply Crystal Serum Ultra?

No. We now apply Envoke ProCoat+ 7 Year Graphene Coating in Packs 1 to 4 and Gtechniq Crystal Serum Light in Pack Essential. Either way you are mostly paying for correction and preparation hours, which are what make any coating look good.

Can a new coating go over an older one?

No. Any existing coating or sealant gets machine polished off first so the new coating bonds directly to clear coat. Coating over a failing layer just means both fail together.

How soon can I wash the car after coating?

Give it a week before the first wash while the coating finishes curing. After that, normal pH neutral washing is fine. We hand over the full care routine at pickup.

Is ProCoat+ worth it on a lease or short term car?

Usually not, and we will say so. Crystal Serum Light in Pack Essential protects well for the years you will own it at a lower cost. ProCoat+ pays off on cars being kept longer.
