Very easy to use ceramic coating
High quality expected from gtechniq. Super simple to apply, apply in cross hatch and wipe straight off. Comes with single applicator, but it’s recommended to purchase some additional to complete a full car. Very easy to work with and wipe off. Great protection for up to 5 years. Increased shine, super slick feeling, chemical protection and water repellency.

Easy to apply and great results when you follow the guideline for application
Superb pro-sumer genuine ceramic coating. I am an amateur car valeter and I look after 6 to 8 family cars. I taught myself to paint correct using a DA 12mm throw machine and a selection of pads and compounds. Now when family buy a new car and the dealer does that upsell of trying to get them to spend a thousand on a ceramic coating they so no, Dad will do it for cost of materials. I have now done 5 cars with GT CSL and if your follow the rules, it is a top class ceramic coating. 1 Wash the car thoroughly and dry. 2 Claybar car to removed bonded contaminants. 3. wash and dry once more. 4 Paint correct using a DA polisher and a fine cut compound. 5 Use IPA or panel prep on each panel, I do this twice. 6 follow the instructions and apply the CSL to half a panel at a time and wait until it flashes over ( 60 secs to 90 secs). Level with one microfibre cloth then buff a wider area with second microfibre cloth. Keep your levelling cloth and your buffing cloth apart from each other, maybe have different colours. Work around the car until you have done all the painted surfaces. Allow to cure undercover for 12 hours. Consider adding two coats of G Techniq EXO on top , again following the guidelines or using a spray topper like G Techniq C2V3. I have another car to do for my DIL so I will be buying another bottle soon. It doesn't matter how old the car is, as long as you do a full decontamination wash and paint correction. the oldest car I have done is 12 years old and it now looks better than showroom condition as there are no swirl marks. I really enjoy working with G Techniq products and my family love having clean , well detailed cars.

Great product
I was a bit hesitant given the price point, but this is truly excellent. Definitely aimed at the DIY customer, with ease of application, but I would suggest at least having some experience. Applied to I30N (same size as Ford focus) and completed the whole vehicle with some liquid left over. Following the steps included was a breeze. If you have a spare weekend to do this I would definitely recommend, the prep is key (I used the Gtechniq panel prep spray). Deep clean and clay bar needed but well worth the effort. Will see how well it holds up throughout the winter then will be buying more to coat other vehicles.

Went on very easily with no fuss.
Went on very easily with no fuss. It doesn't haze and is barely visible on the paintwork which is slightly unnerving. I put it onto a brand new car with no swirl marks or paint defects so it was hard to see a huge step up in the finish. It rained the day after the application and you could clearly see the great beading as a result of the coating. Would recommend

Absolutely top stuff
Applied to an 18-year-old Honda Civic which now looks new. I have got into detailing in my spare time through YouTube videos and am no professional but this stuff really makes me look like one. Absolutely zero issues whatsoever. No problems with application or any problem spots. Water simply will not sit on my paint and the car looks brand new. I do think it is worth mentioning that preparing the paintwork via clay-bar, polishing and subsequent de-greasing will likely take you significantly longer than actually applying the crystal serum coat, but your level of prep will directly link to how well that coat bonds to your paint and therefore your final shine and length of protection. I am also slightly skeptical about the master instruction sheet telling you to wipe on and then immediately wipe off - I left on for a least a few minutes before taking off again and it's clearly worked but that's just me. 10/10 would recommend. I'd upload more videos if Amazon would let me.

Brilliant product - best ever slickness
Brilliant product, was a bit daunted by taking on ceramic coating the car, but it went on like a dream, used with Evo - never had such a slick finish to the paintwork, but as ever the preparation is key. Highly recommend

Its not difficult
Follow the instructions religiously and you will get a very good result. I have done 3 cars myself as a complete amateur and all have worked really well. I add the EXOv5 topper too for the full hydrophobics effect. Don't let anyone kid you that you need to spend £100s on a professional job and ceramic coating is difficult.

Prodotto ottimo, a mio avviso non c’e’ prodotto migliore sul mercato. Il tallone d’achille e’ il tempo e condizioni di stoccaggio. Ho ricevuto in due occasioni il prodotto che stava iniziando a cristallizzare. Cio’ significa che e’ rimasto sullo scaffale per troppo tempo.

Extraordinaire brillance et effet déperlant... Mais gare à l'endroit mal essuyé car une fois sec il faudra reposer l'endroit pour rectifier

Works very well, is also very pricey but this lasts 2-3 years and my car is hit by direct sun in the summer. Solid stuff, worth the high price tag when you don't need to consistently apply a wax/sealant for another 2 years. I only wish the bottle had better sealing ability, some of the product after a few years turned hard, to be expected as the bottle is not completely airtight once it's opened. Maybe a rubber gasket or something would help improve that.
