In my experience, Gtechniq is an excellent product when applied correctly and definitely worth doing. I had one car done over three years ago and water is still beading off the bodywork and windscreen as well as when it was applied despite no special treatment and being subjected to Chicago weather for all that time. $700 well spent.

Cost and value is the issue. I don't see the point in buying the top of the line detail with a 7 year guarantee if the car is not being kept long term. In that case, you're better with a 3 year guarantee that costs less.

I've had my 997.2 GT3 from new and, although it's previously had a Gtechniq detail, it unsurprisingly no longer works. It's taken me all this time to realise it's a long term hold so the car is currently getting the works; paint correction, full Xpel Ultimate Plus PPF (inc roof) topped off with a ceramic coat. I kind of wish I' d done it sooner but better late than never.

Trick is to keep the maintenance up, my previous Leon Cupra had maintenance washes every 6 months by my mate and it looked stunning the day I sold it.

All my cars look stunning as you can see on the other page and the 996 was 15 years old, no need for ceramic coats for cars to keep looking good.

I quite like the £49 self wipe ceramic idea my self I might try it, it lasts a year so all good.
Ceramic coats don’t bead water or offer than hi shine, any way, so it depends what you want on your car.

As the poster a few above found out with the red Porsche, they c2 over the ceramic coat for the shine and beeding.

People seem very confused what the ceramic coat is there for, as I said on page one, you have to cover it with some thing else to get the best finish, shine and water beading.

It’s just a extra protective layer hence I lol at people who ceramic coat over ppf and pay £1k to do that. I am sure this must stop the self healing of ppf in some way.

If you have ppf or ceramic coats, you still need a top coat of something, wax, si02 or C2 or what ever you feel like.

Ceramic coating over ppf is a joke but these top detail shop still do it !

To take a quote from the web site who make the product.


Crystal Serum Ultra can be applied either as a stand-alone paint protection product, or for the best hydrophobic performance, it can be over coated with Gtechniq EXO or C2.

COATED OVER , get it yet !

Hence why my cars look amazing, I just skip the hard protective layer, but will use a wax ,si02 or on my white cars a acrylic coating. Which is also what I used on my yellow GT4.


if yuu have PPF then you seal that with the products made for it. and also top that up with a coating also. it's an acrylic polymer, like I use on my white cars.

there is no easy fix, for fit and forget products, hence why I liked using the si02 spray and it's no effort but gives the finish.

who is paying for that though.

they fitted a ceramic coat as asked, (a protective layer) no one asked them to deswirl the car before hand.

when I had ppf on my GT4 front bumper no one did a detail on it 1st !!! lucky I had machined polished it myself any way.

very tricky subject hence why Topaz charge what they do, it's all inc in the price.

Did you ask for a detail or just a ceramic coating ?

A correction detail would be £600 min before you even start with any coatings.

Gtechniq specify their ceramic coating should be applied to swirl and hologram free cars and all of their detailers / approved shops should follow the same.

I'll let OPC and Gtechniq argue this one out.

it is a mess I feel sorry for you in the middle, also I would guess the OPC would buy in that service from a 3rd party.

Lei OPC use Reep if the cars ceramic coated.

Sales guy at Silverstone kept mentioning Reep as well, he did say that the guy who "polished" my car had spent 4-6 hours on it, I showed it him in the sun and he agreed it didn't look good.

Hopefully management agree to fixing it, it looks good standing far away but up close its not so good.

Just to pick up a couple of points.

You get beading with IGL Kenzo and Gtechniq ceramic coatings without anything on top. The IGL is exceptionally shiny

only to a point on ceramic due to having very smooth paint after a correction detail and the Ceramic being very smooth and shiny anyway.
Hence why C2 or all the other products you put on top of a ceramic coat to get the wow finish.

Water will always beed of a very smooth surface to a point. I still think 90%people are unsure what a ceramic coating is.
Most say for the shine and ease of wash, it's neither, it's a protection layer for the paint from lazy washers who put swirls in their cars.
the just detailed shine comes from the correction polish ! as always prep of the paint gives the flawless finish.

It's on the manufacture web site, not my words.

looking at Kenzo it's a 100% silica product hence the "HYDROPHOBIC QUALITY" it's not a ceramic coating it seems.

there are 30 to 40 of these products now, it's trying to dig out what they all do and what one wants to use.

There are many single coat products that are sold under the general topic of ceramic. Gyeon, CQUK, Nanolex come to mind. These brands also have a 2 coat product. A base layer which doesnt bead that well but provides UV protection etc then a top coat that gives the beading or Hydrophobic effect I think you are referring to those here.

From my point of view for a daily driver I wouldnt be looking at these 3-5 year products as I stated above, but the One year products like Gyeon Pure, CQUK V2/3 or Nanolex are excellent. I particularly like the wheel and trim versions as they make the cleaning of wheels extremely easy and the trim darkens and looks like new for 9-12 months, depending where on the car the trim is.

I do agree with you on the subject of PPF then coating it, just seems like a way to extract some cash from people, BUT if people want to spend there money on that, who am I to dissuade them.

You do know that silica is the main ingredient in ceramic? The IGL website describes it at ceramic.

Kenzo is a ceramic sealant, it seems you also fall into the category of people who don’t know what ceramic is. wink

Silicon dioxide SIO2 is silica. It’s also the primary ingredient in glass and ceramic.

Interesting - 911r spent the whole thread with a superior attitude saying people don't know what ceramic is and he does, and then when its pointed out that he doesn't either he goes very quiet smile

Fundamentally, if you are thinking of any sort of semi permanent coating, be it ceramic or polymer they you should try and look at treated and untreated cars, read the reviews, read the manufacturers specs and claims, but don't try to claim you understand the science.

Interesting thread really.

I was a total sceptic of Gtechniq until i had it on my car. Basically thought it was a waste of money and their products were overpriced. That was 2.5 years ago and ive never used a wax or traditional product since. I can only speak from my own experince and i'll never go back to traditional waxes. Now ive converted friends and family to "ceramic" coatings, so much so that my dad is actually having his AMV8 done right now by Boyd at BR Detailing who is using Siramik HR

Sure you dont NEED to have your car coated and it sure isnt for everyone, you pays your money, you make yuour choice. Just remember though, its your car and your choice, so do what makes you happy.

Bottom line:

Do you NEED it to have a shiny car? - No.
Does it make washing easier? - Yes.
Does it stop alot of unwanted crap sticking to the car? - Yes.
Does it protect against light swirls - Yes providing you're careful and still use the multi bucket/wash mitt method.
Does it stop stone chips? - No.
Does it remain hydrophobic? - No it requires topping up.
Can I add wax over the top? - No

Is it suitable for me? - Your choice smile

That makes total sense to me, however, I have a Mercedes GLE which had a new car detail with Gtechniq three years ago and the coating is still just as effective now as it was then. Considering that it hasn't had a single maintenance wash and has endured the extremes of Chicago weather, I have to put it down to the quality of the application.
