"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.’ Drew’s background meant that he had a good understanding of how the forces, shapes and structures of a surface works on very small scales. He also knew what modifications may be possible in order to add some really useful enhancements. Improvements such as dirt repellency, ease of washing, scratch, UV and stain resistance, along with, long-term gloss and colour stability. So, after surveying many avenues of material science, in particular nano-scale surface engineering, lots of hard work and many thousands of failures, Gtechniq, Smart Surface Science was born. The first product in the Gtechniq range to be produced was C1 Crystal Lacquer, closely followed by P1 Nano Composite Polish."

As several reviewers have mentioned, you have to put some time into preparing the plastic body parts. The instructions list a bunch of exotic products that Gtechniq sells ($$$) for the task, but you can improvise save some money. For example, I had already tested another unsatisfactory product on the front bumper, so I needed to fully remove the remnants of that product. To do this, I just grabbed what I had in the garage:
1) scrubbed the bumper with GoJo (the hand cleaner) and a stiff bathtub scrub brush. I used GoJo because it cuts through almost anything, especially oils. It also has pumice to help in the scrubbing action and it rinses well with water (honestly, the main reason I reached for this is because I have a gallon dispenser of it in the garage). I used this only for the front bumper, to thoroughly remove the earlier product.
2) thorough hose rinse with hard spray (and a quick dry by using my leaf blower... a trick I picked up in an Amazon review).
- - from here all the plastic surfaces got the following treatment - -
3) thorough scrub wash with Dawn detergent. I typically only use Meguiars soap on the painted surfaces, but Dawn is an aggressive oil-fighter, so I chose that for this task.
4) another thorough rinse and blow dry (drying at each stage lets you evaluate whether you've gone far enough with the cleaning).
5) a spray of denatured alcohol wiped down with a cheap microfiber. Buy a gallon of alcohol at a hardware store and put it in a large spray bottle. Cheap and effective as a final rinse. The alcohol evaporates pretty quickly, so by the time you work your way around the car, your starting point should be dry and ready to go.
That's it! Nothing exotic, and not really much work, even with the ridiculous expanse of plastic I was working with (just glad I don't have a Ridgeline).
Now the application of the C4. This part goes quite fast, and you're instantly rewarded with watching your plastics come back to life, so it's anything but dreary. The idea is to put a very thin, even layer on, which is easily done with the supplied pads. No need to go heavy – in fact the full instruction sheet warns that thicker coverage may crystallize and result in a chalkiness.
You spread on a thin coat, making sure it’s even, and then wipe it down lightly with a microfiber (again, use a cheap one for this... one you can throw away). This light wipe down is to even the coat further and lift off any excess... you’re instructed to wait no longer than 5 minutes to do this, so if you have large surfaces like mine you’ll have to work in small sections. It’s easy to feather the edges during the wipe-down, and no problem blending smaller sections. The process overall seems very forgiving.
I would advise doing all this in the shade and on a cool morning. This should give the coating a chance to fully cure before any rain or evening dew. I would NOT advise doing this in a garage unless you have fans and good ventilation – this stuff gives off strong chemical fumes that don’t feel healthy. If it were a U.S. product (it’s from the U.K.) I’m sure it would have the typical warnings for folks in California :) I didn't find any actual cure time in the instructions, but I did get some Windex and soap on one surface after about 4 hours and didn't notice any ill effect.
For the Explorer Sport, I bought the 30ml bottle. Even that wasn’t enough to do all the (ridiculously large) body panels, but I think I was not "stretching" the material far enough at first – it goes against your intuition to push a finish so far. After awhile I could sense when I had enough on the surface, and the material went further. After I ran out of C4 I finished up with the highly regarded Car Guys Plastic Restorer, which is good stuff, but I could easily tell that these are two completely different products: Car Guys is more of a wax or polish, Gtechniq C4 is a true coating... more of a matte clearcoat.
It’s expensive. It takes awhile to be delivered. It’s takes a bit of prep work. But what it does is truly unbelievable... and it’s supposed to last “up to” 2 years. Others are saying it lasts at least a year, which is fantastic. Check my photos – the first one is a bit overexposed so you don't see the difference as clearly as it was in real life. The second shows the finished bumper, the third shows the side panels. In all, a ridiculous amount of plastic... did I mention that?
BTW, those headlights were an opaque yellow mess... I used the 3M 39008 restoration system to make them look that good. And finished with the Meguiars UV headlight coating. Just an amazing combo.
I never should have used this product. The plastic looked better before. Now I have to look at this streaky mess. I suppose I could try removing the product but I am disgusted and just don't want to deal with it anymore. Hopefully with time, it'll wear away. I don't think it'll ever look the same. Only worse.
I cleaned all the surfaces completely prior to applying. I put enough product on to make it look wet. It stayed black for about two weeks then this happened. I'm going to try and contact the company for a refund on both bottles. If you value your vehicle, don't use this stuff!
