I have tried lots of waxes and sealants over the years. My go to recently was Collinite 845 then topped with P21s. Great combo and had really good longevity. Roughly 6 months. Had recently tried G -O's (not putting the name)Ceramic Spray and was easy to apply and lasted roughly 5-6 months . The problem was that G-O's always left streaks on my black hood. Applied several different ways and times and could never get it to not streak on my Audi. Works fine FYI on a grey Volvo. I bought this and applied at the beginning of the year. Its now 9 months in and its still beading and sheeting. I find the depth of shine equal to the P21s, which is fantastic. Although it seems to still be working I decided this weekend to go ahead and do the yearly polish and applied the 303 Graphene spray. I like this product for several reasons. 1. Application-Spray on a micro fiber sponge and just wipe on. It will haze over after several minutes and buff off. For me I could do a large panel to let it dry and then buff off. Buffs off like a wax and the fact that it hazes allows you to see you have full coverage on the paint. Similar to a wax. 2. Clarity and dept. As mentioned my go to for really making my black cars pop has always been P21S. Nothing really like a carnauba wax to give the black paint depth. I am shocked at how much this spray really brings out the black. Looks like a mirror finish. 3. Longevity. My car is parked in garage overnight but this car is the daily driver and has 110k on it. I average 15k miles a year so it sees plenty of rain. In GA so no real snow down here. It lasted 9 months and I could have gotten a few more months out of it. Didnt do anything special over the 9 months just regular hand washes. Great product I do recommend.

Fantastic product - really enhances paint and makes it pop. Ridiculously easy to apply!!! If you follow the instructions and do two applications in 48hrs makes the car look absolutely stunning!!! As an overkill do a traditional carnauba wax on day 3 and the protection really becomes long lasting :)

Very easy to apply, do not use too much at a time. Appears to be economical. Work well for me.

I liked 303 products for a long time. When I read about this product being released, I knew I would try it. Very pleased with how well it heads water and the longevity of a thorough application. But be aware — this is not a two second wipe on/wipe off product. Do it in small sections. Buff it thoroughly as per the instructions. Otherwise it will look very dirty. Learned this the hard way on my white vehicle. That said. Even on a white vehicle, this does not impart any off-tinting off the paint once it’s fully applied. Is it as good as a professional ceramic coating? No. But it also costs WAY less. Was easy to maintain too — for the first three months after applying, washing the car consisted of rinsing it with a garden hose. No soap, bucket, or hauling out the pressure washer. If this is your first time doing something like this. I strongly recommend using a clay bar kit to clean the contaminants off your car’s paint before going through the work to get this on and buffed out.
