I put it on right after putting on their ceramic coating it really made it pop! The towels are very plush seem to be pretty good. I used 3/4 of one bottle to do my F-150. So about $12 a use or so. But seems to do the job took out some minor scratches on the ceramic coatings. But it really pops the shine on top of that ceramic coating and it builds up according to what the company states. From what I've seen so far I would agree. 👍👍👍 I give it three thumbs up.

It leaves a nice gloss finish that is very smooth and will repel dirt and water. I sprayed on the car, spread it evenly with a microfiber towel which I also sprayed, let it sit for about a minute and then wiped off with clean dry microfiber towels. I had no problems with streaking or smearing. I did it in the garage when it was around 60-65 degrees, so don't do it in direct sunlight on a hot day and expect the same results. I don't know if this is going to last long or not, but I garage this car and only drive it in the summer, so it should for me. Even if it doesn't, it's easy enough to go over the whole car again after a wash.Basically, it does what it claims, it goes on easy, wipes off easy, doesn't streak and leaves a good shine, so what's not to like? I can get two or three applications out of one bottle, so I figure it only costs about what you'd pay for a cheap laser wash, although I'd use it on a clean car or for removing light dust (detailing).3/6/20 Update: I purchased an applied the Ceramic Coating as well. I applied with a folded microfiber towel and removed with a clean microfiber towel. It goes on as a liquid, I left it sit for 2 minutes and then easily removed with the dry mf towel. It looked good when I finished, but didn't notice a huge difference. However, after letting it sit until the next day, the product must've cured because the finish was noticeably more glossy. I haven't tried the water test yet, but this really gives the car a nice shiny finish...and it took about an hour and I only used about 1/4 of the bottle for my entire car. I suppose the better looking your paint is when you start, the better the results, so buff out all the imperfections you can. My car looks great, can't wait for Summer.

I have a 2019 Ford Mustang and used the product to detail the car. The shine that resulted was fantastic! Although my car wasn't dirty, the fact that I didn't have to wash it first before using it was a plus. It was very easy to use and took me about 50 minutes to detail the whole car and as you can see, the finish was outstanding. I would definitely recommend it. ps...I didn't respond to 'Longevity' as I've just started using it.

I have purchase the QuickCoat SIO2 product a few times and I will continue to do so. This sttuff is amazing, easy to use and at an affordable price. I use the product almost daily as I am meticulous at keeping my car clean. I believe this ceramic spray cleaner & protectant is the best on the market. The SIO2 QuickCoat offers superior shine and paint protection from the elements. I am so confidant in PROJE products that I recently purchased their "Ceramic Enthusiast Pack - Instant Hydrophobic Protection, Brilliant Depth & Shine" and I can't wait for those items to arrive. My friend's and neighbor's all compliment how shiny my car is and when they ask what I use I proudly tell them PROJE products. I highly recommend the QuickCoat and other PROJE products for your daily car care.

I have a black car. Black looks great when clean and shiny.Though my car has never seen a brush, there were fine scratches and swirl marks.I've been experimenting with different auto polishes and detailing products that are eady to apply and leave a great shine. Si02 is the very best I've tried do far. My car finish is like a mirror and all the swirl marks and fine scrstches are gone.We recently had rain and the rain rinsed away all the dirt and dust and my car is still gleaming.I highly recommend this to anyone that wants to keep their ride looking like a million.
