Gtechniq Gtechniq was founded by quantum physicist Drew Gill in 2001, out of a total dissatisfaction with the performance of paint protection products at the time. Everything from waxes, to new-fangled polymers and PTFE based miracle treatments, nothing on the market offered any meaningful durability, either in looks, or protection. Worse still, he found that most of the products actually performed poorer than the paints they were supposed to protect. From this discontent came a simple idea, ‘To engineer the world’s most beautiful, perfectly finished, smartest and most intelligent surfaces. Surfaces that do much more than simply look great when new.’

The Gtechniq "useage/coverage" thread

Right guys,

My aim here is to be a 1 stop place for people asking "how much will x ml of Cx cover" and so forth. please give me any tips etc and i'll amend the 1st post. mods - please make a sticky

C1
to coat a car of similar size to a new BMW 1 series coupe i used about 13-14ml of product to do the entire car. a 25ml bottle will be enough for MOST cars out there. 25ml may even coat 2 small cars if used correctly. a little goes a LONG, LONG way!

EXOv1
A 410ml can should be enough for approximately 2 layers on all exterior surfaces on 6 cars. The 180ml can will obviously do a bit less but more than enough for a couple of cars.

EXOv2
The 30ml bottle will do 2 coats to one car up to SUV size.

C1.5v2
typically 50ml per car for a car around a 3 series/5 series BMW size. i personally used about 40ml on an E92 M3 and found it was more than enough.

C2v3 (neat)
same size car, 40-50ml is enough to coat a whole car generously. 30ml should be more than enough for large cars (e.g. merc S class, BMW 7 series etc)

C2v3 (diluted)
you'll use a tiny bit more than C2 neat, but not a great deal more. i'd recommend making this up at between 1:2 and 1:3 (1 part C2v3 to x parts water) concentration. C2v3 does "go off" if diluted in but it should be good for a couple of months; so keep a bottle of the neat stuff, then when you need the diluted stuff, mix it (preferrably with de-ionised or even distilled water) and use it in the next week or so. 30-40ml should manage on most cars however.

C3
a little more than C2, i personally found about 30ml to coat my car.

C4
a little goes a very long way. 15ml will be enough to do the plastics on most cars, and a heck of a lot more. cars with lots of plastic (e.g. freelander) may need 25ml. but i'd say 90+ % of cars out there, 15ml will be enough by some margin. on my car, the only plastic trim i have include door handles and wing mirrors. to do this i used about 2ml of product, give or take.

C5
15ml should coat 4 wheels of up to 18 inch diameter (both inside and outside faces of wheels) and possibly larger (i coated 4x 19" alloys on an E92 BMW M3 with about 15ml) unless the wheel is a rather tricky/intricate design, in which case, order 25ml just in case.

G1
15ml bottle is enough to cover 1 whole car properly (i.e. 3 coats windscreen, 1 coat side windows and 2 coats rear screen) OR 2-3 cars windscreens, each with 3 coatings.

G5 (formerly G3)
more used than G1, but the smallest 100ml bottle is enough to do many, many cars over.

G4
100ml of the glass polish should see 4-6 cars without too many issues (maybe more), depending how dirty the glass is. it's best to clean the glass prior to polishing to stop wasting product.

I1
500ml will coat a complete car interior 2-3 times over.

T1 tyre and trim
hard one to judge due to the variance in tyre sizes. i guess i found i used about 75ml (give or take) to do 2 coats to 4 tyres, the rear tyres are 255/45R18 and the fronts 235/50R18. you may use more or less, depending on gloss levels, absorbancy of the pad you use etc.

W2

500ml bottle goes a very long way. Here are the recommended dilution ratios. please bare in mind it may be better to make the ratios up as you need it (i.e. don't make up several litres at 10:1 as it may go off after weeks/months. i'm not 100% sure on this though, but C2 diluted does "go off")

GTechniq suggest the following dilution ratios:

Dilution recommendations
Fiberglass 10:1
Air conditioners 10:1
Driveways 10:1
Paint oxidation 5:1
Window cleaner 120:1
Carpet 7:1
Grease 2:1
Heelmarks 5:1
Grills 5:1
Walls 20:1
Counters 10:1
Stainless steel 20:1
Outdoor furniture 20:1
Vinyl 10:1
Hoods 5:1
Chrome 20:1
Tools 10:1
Smoke films 10:1
Alloy wheels 10:1
Cloth furniture 10:1
Leather 10:1
Wax stripping 5:1
Steam cleaning 50:1
Engine bays 1:1

please add any more products. these are the ones i have used so have put up. At some point in the near future i may put up a detailed instructions thread, in hope they will stop the endless "how to apply xxxx threads". hopefully this will stop the "how much xxxx to coat a car"

Hope you find this useful.

Ross.

It isn't really a post too disagree with . Its more just a guideline. Different people will use more or less product. for instance I used about 14ml and got my Megane and Corsa c and a Kawasaki 600 ninja done...

Excellent post Ross - I'll Add to this with a few comments of my own based on a smaller car (Mk6 Golf)

C2

About 30 ml for my Golf - then 10 ml into 90 ml of de-ionised water does 2 QD wipe-overs within the month or so shelf life.

C4

My Golf doesn't have as much exposed plastic as some cars, I used around half of a 15 ml bottle, this included the gloss black B-pillars, headlights, tail lights, bumper protector, grills, scuttle, brake/indicator repeaters, reflectors etc.

C5

I still had a good amount left in a 15ml bottle after doing my 16"/205/55 wheels.

I've used W2 quite a bit - a brilliant product ... ... ...

W2

A 500 ml bottle of W2 concentrate goes a very long way. Dilution ratios vary upon use, but I've found it's a damned good APC and particularly good on stubborn stains. Besides car use, we've used it on various household stains such as dog-puke on carpets, coffee stains, mould on tent fabric and old dried-in deer blood on car load-area carpet which I didn't know was there (my old RX4).

GTechniq suggest the following dilution ratios:

Dilution recommendations
Fiberglass 10:1
Air conditioners 10:1
Driveways 10:1
Paint oxidation 5:1
Window cleaner 120:1
Carpet 7:1
Grease 2:1
Heelmarks 5:1
Grills 5:1
Walls 20:1
Counters 10:1
Stainless steel 20:1
Outdoor furniture 20:1
Vinyl 10:1
Hoods 5:1
Chrome 20:1
Tools 10:1
Smoke films 10:1
Alloy wheels 10:1
Cloth furniture 10:1
Leather 10:1
Wax stripping 5:1
Steam cleaning 50:1
Engine bays 1:1

You might not like my posts, I won't lose sleep over it. Strangely several hundred have thanked me for them - I'll even thank you for yours.

You might want to differentiate between C2 concentrate and diluted for QD.

I'd agree with the above for G1, G4 & C2 which are the ones I have used.

G1 & G3

I have G1 on front and rear screens, G3 on side windows and mirrors - G3 very effective on side windows, water just flies off of it, but wouldn't stand up to wipers on front/rear screens. If you don't have a wiper on your rear screen I'd be inclined to use G3.

I1

Great on all fabrics including carpets and mats.
