CARPROHydrO2 Touchless Silica Car Sealant - Spray-On/Rinse-Off Paint Sealant, Concentrated Car Wash Detailer, UV Protection - 500ml (17oz)

As a professional detailer, who installs full ceramic coatings. I not only use this, but recommend it for two different things. It's a great professional or diyer topper for ceramic coatings. It's also a great option if a full ceramic coating is out of your budget. Real world expectations of durability is about 4 months. Assuming no harsh chemicals are used to clean vehicle. You'll get all the protection from a full ceramic coating. Minus the durability and swirl resistance. Keep in mind before purchasing. You will need a power washer to apply this product. As it's a very simple and touch less install. Shower it's pressure activated. Hence the need for. Power washer.

I keep Cquartz with periodic coats of Reload on my vehicles and just purchased a new truck. Still a little cold here so I wanted to wait a month or two to do some paint correction and coat it the truck with Cquartz. Thought I'd try this to get me there. I was pretty amazed how great it did. Very simple to apply and results are amazing, surface is very hard, deep shine and slick as glass. I applied in 40 degree temps not sure what the top end of temps are but I'd guess 80 max. Warmer the temps faster you'll have to work. I did spread the mist with a wet micro towel to insure coverage. Not sure if its necessary but definitely worked. I also made sure to keep the whole truck wet throughout the process and do a really thorough rinse. I also recommend carpro PERL for your tires and plastics, easy application and long lasting.

This product is amazing and works as stated. Left a really smooth feel to my paint and water beads right off.

Edit #2: I been using the same 500ml bottle fog months now. I've used it on several cars that I've cleaned. Hydro2 is now an irreplaceable item in my inventory. Sray on, then pressure wash off. Like my review says, claying before application helps a bunch. I need another bottle. I'll probably buy to 1L next time. More than 5 stars if possible.Edit: expired or not, this stuff is awesome! I don't know if I can justify the price (about $7/car) but it is really easy to use. I used a 7:1 ratio and it worked beautifully on my vehicle. I had previously cleaned, clayed, polished, and sealed my suv before winter. I cleaned all the winter grime off and applied this. The only thing I have left to wonder about is how long it will last.I haven't had the chance to use this yet. But there is an expiration date on it that says it expired over a month ago. Should I be worried? If it's gone bad, I don't want it ruining my paint. I'll update my review with the good or bad news after I put it on a test panel.

I love this stuff.I live in South Florida and don't have a garage. The elements relentlessly attack my precious 4 series. This product can survive nearly an entire summer without reapplication, remaining water and sun repellent. A single application easily lasts any other full season. The paint looks like the day I bought the car five years ago, dings aside.Application requires a thorough wash, then about five minutes of prep and ten minutes of work. I use a garden mister to spray it on. Rinses right off, no buffing. Magical. If you haven't used a product like this it will stun you the first time you see water roll off it.Hard to imagine using anything else. Sometimes I wax over it for a different look, but it's not needed.

Great product that gives a good shine.Pros:easy to apply (must dilute 1:6) but takes less effort than most waxes to applygives a nice silky feel to carCons:must still wipe while wet (this is important to do prior to it drying otherwise you will get water spots/streaks)priceyI used it on 4 of my vehicles (2 of which are black). The first time I did it and did not wipe while still wet just after the rinse part. It dried and left water streaks. On the second black vehicle I made sure that just after the rinse and before it dried, I took a fiber cloth and wiped it dry. I dont' know how it will hold up to the PNW rain but it was so easy to use that I'm way more willing and likely to use it after touchless car washes. I will update the review when more weather/time as passed.Update 7-13-182 months have passed.900 miles and 2 weeks rainy PNW weather. I went to wash the sequoia for the first time after the initial application. The water still was beading off the sealant. Made it so much easier to wash and clean. I reapplied the sealant but this time 5:1. Instead of applying it and washing it off, I sprayed it and buffed it in with a microfiber cloth. It did make it easier to prevent water spots on the black SUV doing it this way vs. the wash off technique. I realize this is not how the manufacturer intended to apply it but I wanted to see what would happen. The finish felt and looked as good with the wash off technique. I'll update the review to see if this technique will last longer or provide more of a hydrophobic effect.

Very easy to apply. Left a nice shine and smooth-slick feel to the touch. Now we just need to see how long it lasts. 👍

This stuff is amazing. Easy to put on. Dilute in spray bottle. Only do one panel at a time. Heed this warning. One panel at a time. Do not leave on more then a minute and rinse with the highest pressure setting on your water hose. Supposed to last 6 months so we will see. I’m 3 weeks in and it sheds water so good still. Clay your car first. Also an easy task. This stuff makes your paint super slick.
