Can this be applied to a car that is vinyl wrapped?

Yes, but dilute with 2 parts distilled water to one. Spray on micro fiber wipe then wipe on car. Brilliant finish.

Can this be use as a maintenance after a wash even when i have gtechniq crystal serum light already on?

Please allow me to give you the proper information as I am a G-TECHNIQ certified installer and if you have coated your car with Crystal serum light and then topped it with two coats of EXO V4 then you would wait approximately 7 to 10 days to wash the vehicle with Gtechniq g-wash and then apply your liquid Crystal c2v3 on a completely dry cool surface on half panels at a time only using as little product as possible because a little goes a long way, after 1 hour you can apply a second coat which is ideal, but after that you shouldn't apply any more coats of c2v3 for at least 2 months and the problem with applying it every time you wash or even once a month is you will get a buildup and that build up becomes a sticky surface and you will notice that dirt will be attracted to it, these are instructions directly from Gtechniq and no other direction should be followed other than these, this is the highest content of any ceramic detailer you can buy in any product. Please disregard any other answers within this post as they are useless and somewhat quite disturbing

How many cars can you do with one bottle. i have a jeep wrangler 4 door.

It depends on if you bought the 16 oz bottle or the one quart bottle but if you're referring to the one quart bottle and you are using it properly without going crazy with it because that's not good as the surface will get build up. On one quart bottle in my business does roughly 7 to 10 cars easily sometimes 14. I am a G-TECHNIQ certified installer of their ceramic coatings and I can assure you most of the people are putting way too much of this product on their vehicles the best thing to do is get a short nap microfiber towel and prime that towel with about four sprays and then each door or half hood should get no more than two or three sprays and then wipe into the panel very well and immediately with a soft microfiber towel buff off and straight lines. After 1 hour you can apply a second coat and now you should not use that product again for at least 2 months as the surface could become sticky and attract dirt if you follow this useless procedure people are doing and spraying it on once a week.

This stuff good for windshields?

yes you can use on windshields most people use a glass sealant on there windshields will last longer

Easy to apply and slick shiny results.

Wipe on, wipe off. Easy to apply and makes a super slick & shiny paint finish. Took about an hour to wash car and then apply the Gtechniq C2 Ceramic Sealant to all paint and glass surfaces. There may be better products and we'll see how it holds up, but satisfied so far.

Good shine

It goes on easily and produces a deep shine. Not sure how it’s going to hold up since I just used it but so far so good.

I was skeptical, but wow!

I recently had my Lincoln ceramic coated and was honestly skeptical about whether the investment would be worth it. But after using this product, I was blown away by the results. As a self-proclaimed “car guy” who’s tried countless detailing products over the years, this one truly stands out. The finish, the shine, the protection—it’s the best I’ve used. Highly recommended.
