Gtechniq C2 Ceramic Sealant for Cars 5L | Quick Spray-On Paint Protection, Hydrophobic Barrier Repels Dirt & Water, Long-Lasting Gloss & Easy Application

Very easy to apply, just spray and wipe off. Doesn't leave any residue although sometimes you get an occasional smear that a quick spray of Gtechniq QD sorts out. I'd say it provides around 4 months protection, may be 6 in summer. I apply two coats, one straight after the other. You need a dry, overcast day to apply it or do it in your garage. You do not want it to get wet on the day. Warmer weather seems to give a longer lasting bond, so I wouldn't apply this in the colder months unless it is a really mild day. Gives protection against swirl marks and fine scratches, as well as hydrophobic protection. Makes washing the car a lot easier as dirt comes off better. In fact, very rare to have to do anything but snow foam and pressure wash to clean the car. A good alternative to more expensive ceramic coating that's hassle free and does the job. Works on painted, glass, plastic, metal and carbon surfaces. Apply two coats twice a year.

I've used numerous paint protection/waxes over the years from big brands but none is so easy to apply or has such longevity as this Gtechniq Ceramic sealant. It's just super easy to apply, wash and dry the car, spray on and wipe off with the same cloth, no buffing required but I keep an extra cloth which is dry just to run over post application, that's it! No annoying wax requiring a lot of elbow grease to remove and leaving traces where you missed a bit buffing off. Also, this lasts for ages and the water repellency is easy to see for weeks after. I've used it in sunshine (against the rules) and it is still super easy and delivers the results. I've done 4 cars and no sign of it running out yet either so overall great value. Given the ease of use and flexibility of the product I now tend to use this after every wash and my cars have never looked so clean!

A great product, easy to apply and definitely adds to the shine. The supplied trigger spray head didn't work. Fortunately I had a spare.

Superb product! Applied more than a week ago and in that time have had rain, snow and bright sunshine and this stuff takes any weather in its stride. Rain water still beading wonderfully despite the car having endured various temperatures, motorway spray and grime, and grit salt from the past few freezing days. Really easy to apply and the results are seen instantly. Great value for money, and by far the best detailing product money can buy.

Very easy to use and quicker,leaves a very glossy shine,excellent product,excellent results.

Easy to apply and take off. Leaves the car looking really good with out any marks

Perfect and so easy to use after car ceramic coated to keep it in top shape and good shine and repellent

Update 04/02/2026 - Gave up waiting for a nice dry day when it wasn’t too cold and or wet and applied it in my garage after first thoroughly washing and thoroughly drying the car. So does it work ? Well I’ve not noticed any great improvement over normal car wax! Is it easier to apply? Undoubtably. Is it worth the money? Well if you are in a hurry and you don’t mind the fact that it lasts no longer than a good quality car shampoo at dispersing water then yes I suppose it is. Does it do a better job than most fast wax products? No definitely not. To be honest I had a ceramic coating applied professionally on my new car, at vast expense, it lasted no more than six months, and I’m being generous, then it was going to cost me heavily to get the remaining coating off of the car before they could reapply, well that’s what they told me. I’ve gone back to good quality carnauba wax and elbow grease. The old ways are the best Luke.
