CARPRO HydrO2 Touchless Silica Car Sealant - Spray-On/Rinse-Off Paint Sealant, Concentrated Car Wash Detailer, UV Protection - 100mL (3.4oz)

Been using it every 4-6 months for a couple years

The wheels on my car are forever getting covered with brake dust. The brake dust will corrode the painted wheels if allowed to stay on, so cleaning them is a must-do, AND done fairly quickly after getting brake dust on them. But these wheels are a hassle to clean- not so easy because of their design. Hydro2 is a sealant that gets diluted / mixed with water, sprayed onto the wheels, then kind of forced onto the wheel with a power washer or strong stream from a garden hose. Once it's applied to the wheel, the wheel is "coated" and will allow for an easy touchless cleaning. After I sealed the wheels with this, to clean them, I only need to spray on a wheel cleaner (careful which you use) and then hose it off. Wipe off the excess, and blow the wheels dry with a leaf blower. This is a fantastic product and saves a lot of time. I enjoy cleaning and detailing my cars, but fussing with the wheels is a drag. My only complaint is that the Hydro2 is really expensive (that's why 4 stars not 5 stars) and you only get 100 ml. In my estimate that's enough to do 2 sets of wheels. The results are great.

Loved it so much I bought the big bottle. This does what it says. It beads water like crazy. Super easy to use. Spray on and hose off. Make sure your not doing it under the sun or when the car is hot. It will leave water spot like marks that take several washes to remove.The durability is pretty insane considering there is no elbow grease that needed to apply. I no longer use waxes.

Not impressed at all! Here are the problems with this product:-1) I was barely able to manage to cover 1.5 cars with the entire product. Since this needs to be applied and immediately needs to be hosed off, it had to be done outside. With little bit of gentle breeze, half of the product was getting wasted.2) The overall slickness and the hydrophobic properties are nothing to write home about. I have literally dozens of different detailing products and each one of them can do better job that this one. Some even could do in comparable time3) Even if this bottle had cost me $2.00, I would not purchase it again. At $21, I consider this as a hard life lesson learnt as I had been eyeing this for couple of years based upon the internet buzz.4) I am going to preserve this bottle so that the next time I get urge to splurge on yet another highly recommended detailing product, I can dump water over my face from this bottle and bring to my senses!

The sealant has worked great so far! I use it on my wheels and it saves me a lot of time! Just spray it on and rinse it, it can't get much easier than that! The only downside to this product is the price, but the product itself is top notch!

I must say that I'm very impressed with how easy and effective Hydro2 is. It really was as simple as spray on, hose off. The effects could immediately be seen. Water beaded very nicely and sheeted off beautifully. I used an electric leaf blower to dry the car and water came right off. Really hoping this stuff holds up for the advertised lifespan because it could be my new to go for wax/sealant.However, my only complaint is with the price. You get 100ml (3.3 ounces) for a little more than the price of 16oz of Collinite 845 which is what I used before. 845 definitely can last up to 6 months and you get more than one use out of the bottle. The 100ml bottle was barely enough to do my Ford Fiesta ST. I'd recommend getting a bigger bottle if you're trying to do a whole car or dilute it 4:1.

This is a compelling product, but it is made for a very niche consumer. For this to make sense for you, you have to (1) have access to perfect conditions for application--no sun, no breeze, not too hot, not too humid; (2) have paint that is perfectly clean and prepped; (3) not mind spending top dollar on a sealant; but (4) not want to spend the time to apply a traditional sealant.It seems like this would be perfect for a non-mobile pro or an enthusiast with his own wash bay. But in anything other than perfect conditions, you're going to encounter product drift in breezes (which is wasting a $$ product and will drift onto panels that you aren't trying to work on). I also encountered significant streaking at the recommended 1 part product to 3 part distilled water dilution when I applied on a hot and humid day, but out of the sun. I had better luck at 1:7 dilution, though unclear how this will affect longevity.I will continue to use this to seal my wheels as it does a great job sealing hard to reach areas. I don't know if I will continue using it for my paint.

If I was told a product like this would exist 10 years ago I would have thought you were crazy. I like how it comes as a concentrate so it does not take up any extra unnecessary space in the cabinet. I use it on my wheels and exhaust tips to aid with easy dust removal on the next cleaning as Audi produces an insane amount of dust. It works much better then Gyeon wet coat if your trying to decide between the two go with Hydro2.
