303 Touchless Sealant

I bought this stuff to protect the wheels of my 2018 Mercedes E63. I washed the car, sprayed it on, immediately rinsed it off, and then dried it with a microfiber towel just as the directions recommend. I know I got too much on in places because it ran and actually dripped off. The directions said not to do that warning that it could leave streaks or water spots, but it didn't for me (it might on a shiny painted surface). In fact, after application, the wheel looked much shinier than the other three, and it definitely beads water now. I only did one wheel (passenger front) as an experiment. the process took less than 5 minutes. I'll drive it for a few days and compare the brake dust buildup to the driver's side. Whether it stays cleaner or not, I'll likely do the other three after the next washing just so they all have an equal shine. At that point, I'll revise my review. I'll revise it again in a couple of months for longevity, but for now, so far so good. UPDATE: There was a noticeable reduction in brake dust buildup on the wheel I treated. In addition, it rinsed almost clean with just a spray from the garden hose. That being said, I treated all the wheels. Again, it took less than 5 minutes each. With all the intricacies of a wheel, I had to really pour it on. That resulted in runs and even drips, but I rinsed it really well then wiped it thoroughly with a cloth, and I had none of the water spots or streaks other people have reported. I'm satisfied so far. We'll see how long it lasts. UPDATE 2: I upgraded my review from four to five stars. This stuff works great on the wheels. Even months later, the brake dust doesn't stick nearly as bad as it did before I sprayed this stuff on. In fact, I think I'll give it a second treatment tonight just for good measure.

Good shine, easy installation.

This product is great. Lasts a few weeks, but perfect for wheels. I used as a topper after washing the car and the hydrophobics came back and looks great!

It's a good touchless sealant. I would say comparable to Gyeon WetCoat and CarPro HydrO2. I would not day better value that HydrO2 because that is diluted 7:1 when you buy the concentrate. It does have better gloss than most all of the other touchless sealants. It performs as expected. No complaints really on its performance. My only complaint is the way the trigger sprayer is. It isn't bad, but if you apply out outdoors like most people will, you have to be close to the paint because of the very wide angle it sprays. I put it into a Zep bottle that I could narrow the misting pattern down on to be more efficient with the spraying. Not a stream, but a more narrowed misting. If you apply this with even a slight breeze, you have to be close which means you need more to coat the vehicle fully. To each their own on trigger sprayer preferences. I would recommend it as a sealant option that's easy and affordable. I used the bottle to coat a semi with a sleeper, and a Subaru WRX. I still have enough to maybe do the Subaru again. Much quicker and easier than applying a creme wax or sealant. A cheaper alternative if you would have time to buff it would be Turtle Wax Seal N Shine. Overall, 8.5/10, my only gripe being the trigger sprayer, which honestly is a choice of personal preference.

Follow instructions, because if you don’t yes water drops will appear. Was pretty difficult to get them off after a few minutes. This is a fabulous protector for sure. It’s been applied for 2 days. Expecting rain in a few days. I have high hopes it will exceed my expectations. If anything changes, I’ll update. A little product goes a long way, was a decently large bottle of product. So update, 5 days later. From light mist to heavy downpour it did great. I could tell it was doing a good job, for everything wanted to bead off. Even my window wipers normally make some sort of noise. Almost dead silent, like the layer on the windshield is buttered up and the wiper is just gliding across. When I touch it with my finger it isn’t greasy or anything (except when first applied). I don’t think I need to keep looking for other products, for now this is perfect. Only real test that’s left is to see longevity. Hoping I get close to the 6 month mark, I’d be happy with even 3 months. Original purchase in May 2019. 2nd update may 2020. I’ve applied 2 times in the year, was trying for a 6 month interval. It’s more of a 4 month life after applied. Well for my car. Waited 2 extra months to make sure it was completely off. Properly applied makes black cars look so nice. Makes rubbers dark and new looking (only for a short time). But rest of the vehicle omg it’s so nice. By the way, my car is 5 years old. 70,xxx miles. Looks almost as it did when I first bought it. Never garage kept. Always outside.

Excellent. I've tried a bunch of hyped SIO2 products like this & they all fall short of their performance claims. This one does not - it works great and is just as quick and easy to apply as stated on the bottle. I bought a gallon of it for around $50 and at that price it's a total no-brainer. Works as well as a fresh application of RainX on glass with considerably less effort. I'll update after some time if longevity falls short of 3 months or so on glass. If you don't see an update assume the product has met or exceed my expectations on that measure.

This can last for months depending on your situation but the effects do wear over time, I like to use it once a month. I have owned a car that was professionally ceramic coated and I honestly like this product better. To those complaining about streaking I had the same problem initially, and I can not blame it on 303, its due to poor water. You should use distilled water for best results for this if you wash your car at home you will want to purchase a DI filter, I bought a DI RINSE PRO 100 for about $600 which is expensive but you will not have to worry about drying your car or any pesky streaks or water spots! Just wash your car thoroughly make sure its spotless then wet/rinse your car and spray this 303 sealant on panel by panel and rinse off thoroughly with distilled water (via DI Filter or Rinse Free Car Wash) and your car will look like it was professionally polished! best part? you can use it on rims to make cleaning brake dust a breeze, you can use it on plastics outside along with rubbers to protect them from fading from the sun, and on your windshield? better than RainX! you will rarely need your wipers when it rains. This stuff is just the best if you use it correctly. Everyone always asks me what my secret is and assume that im constantly waxing my car... nope! 303!!!

Really impressed with this product for: 1. Ease of application 2. Finished shine 3. Makes future washes easier 4. Lasts for a good while (Roughly 6 months for me). I've used this product on three vehicles and have purchased this item twice. The use of a pressure washer (What I use) versus garden hose may have an impact on how well the product is distributed among the vehicle surface, as the lower pressure of the garden hose may not distribute the product as well. Purchasing by the gallon has been the best value for me.
