303 Products Graphene Nano Spray Coating for Cars, Advanced Graphene Coating Spray – Enhances Gloss & Depth, Water Repellent, UV Protection, Helps Prevent Scratches, 15.5 oz

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.

Dries quickly and application is easy. Covers great.

Being an avid detailer for over 30 years, I am a pushover to try new products like these. Now, to start, yes, it does "work", and it does leave a nice finish, but is it better than anything else out there? Or better than something like P&S Beadmaker? I would say I'm not convinced (Just yet). . For starters, since this does seem to have the nano particulates in the fluid medium, you want to shake it well, and you want to wear gloves, as you will get powder type stains on your hands, similar to handling a printer inkjet cartridge. It's not as "bad" as that, but it is noticeable. . Secondly, this product is in a petroleum type medium (Seems to be oil based). Another reason to wear nitrile gloves, as you should with most if not all these products. . Thirdly, do not use foam type applicator pads or microfiber covered foam pads. The reason being is that the fine nano particulates will immediately soak through the sponge medium and head to the center, so in essence all you'll get is the oil based medium, which sort of defeats the purpose. . Fourthly, this seems to permanently stain microfiber cloths, even when I wash them in hot with a micofiber detergent designed to wash microfiber, but that's not a huge issue but something to be aware of. . I have applied this to both the paint and plastic headlamps, tail lamps, mirror caps, etc. It works very well and does leave a nice coating. I haven't had a good amount of rain yet to fully test the beading capability, but it "Seems" like it should be adequate. Application is fairly easy and the medium is similar to something like a light "Spray wax". I used a relatively thin microfiber cloth to cut down on the material soaking and loss of product. Simply wipe it on, thoroughly, working it in and let it dry to a haze. I removed with my fine side of a good quality microfiber towel, and then finished it off with spraying lightly, some distilled water vapor and then getting that nice level set wipe down. . Good product, but I'll update as I work with this more, especially as the weather gets better.

As the vast majority of other commenters have stated, this is another incredible product from 303. Results in a deep lustrous protective finish. A few thoughts on those who have commented on difficulty buffing the product and the "sticky" finish. (1) First, although 303 states that Graphene Nano Spray Coating can be applied to any finish, its best to use the product as a "top coat" for another smooth base coat (wax, ceramic coating or sealant). If you are starting off with a rough finish or base coat, don't let it dry/harden more than 5-minutes or so after applying or you'll likewise struggle to buff the coating; (2) Second, while using the product by itself results in a protective coating with an amazing mirror-like finish, to get a glass-smooth finish its recommended that you apply 303 Graphene DETAIL Spray over the top of the 303 Graphene Nano Spray Coating; And (3) Third, if you have a white or light colored car, the finish will be just as good as any other color; however, the graphene oxide will find its way into joints and nicks which results in a grey or blackish appearance within those joints or imperfections (particularly if you've followed the instructions and shaken the bottle well to distribute the graphene oxide in the bottle). As a result, its critically important to pay attention to the edges of body panels and any surface imperfections to make sure you remove the graphene. Finally, as a piece of bonus advice: 303 recommends 2-3 coats of the Graphene Nano Spray Coating. This is what I've chosen to do as well as adding a final top-coating with the 303 Graphene Detail Spray. In the future, after every hand wash, I intend to spray a new coating of the Detail spray to maintain the coating. I'll repeat the process each year until its time to re-apply my base ceramic coat. Hope this helps.

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.

First, the bad. Like some others, I used this on my two cars and the sprayer broke after several applications. A quick email to the company from their website asking for a replacement spray nozzle resulted in a fairly quick response from Conrad at the company. He asked for my address and a week or so later a fresh bottle of the product arrived via UPS. he acknowledged that they had a supply issue with the spray heads. The good news is that this product works very well and now four months after a single application to both cars, the water continues to bead up and allows me to use a Makita hand held blower or leaf blower to chase most of the water off before hitting it with a micro fiber towel. I am not a shill for the company, just an ordinary consumer who appreciates a good product and good service when there is an issue. To those who bad-mouthed this product, give Conrad a heads-up and get taken care of. You won't be disappointed.

I was looking for something to keep the shine and add protection to my new truck and my sports car. This coating goes on much like a wax - spray it on, let it dry, then buff. This is an easy product to apply which I really like. As soon as it's buffed you can tell the difference. The surface is very smooth and shines beautifully. It's hard keeping dark colors clean, but after a couple of weeks this seems to be doing the trick quite well. The hardest part about this product is preparing the surface in advance. Make sure your vehicle is CLEAN. This should include a good wash and a very thorough detail with clay bar or something similar before applying the 303 Graphene coating to remove any unseen contaminants from the surface. This will ensure you have the absolute best surface to apply the coating to. I also like that this can be applied not only to the paint, but to the plastics, glass, trim, etc. as well. This really expands the protection it offers to the whole exterior of the vehicle.

For context: Both cars are parked outside permanently in Southern California and in areas where there's high contamination, one near the airport, and the other near many industrial warehouses (lots of semis that come through the street). I've always prescribed to the wash and carnauba wax since I started driving. On my last car, I had a professional ceramic coating that was maintained yearly by a local shop - it got tiring and expensive to maintain the car without a garage. This seemed like a promising product. Applied first time on two cars, 7/22/24. Because it was warmer, the hazing was quicker, so I did half the car at a time excluding the bonnet. To clay, I used a NanoSkin Fine scrub sponge with lubricants: Mother's Quick Detailer and Meguiar's Quick Detailer, found at your local auto parts stores. I used a Batoca cordless car polisher to apply/buff the NuFinish NF-75 polish and then buff off this coating (two coats). I didn't read the other review where it states this product would permanently stain the microfiber pad when applying. Initial Result: The shine, glossiness, and hydrophobicity was more apparent on the 2016 Lexus - it usually gets washed every few months at a hand wash place and waxed twice a year. On the 2023 Mazda, the shine, glossiness and hydrophobicity were there. The Mazda gets washed every few weeks at a self-car wash. By early January 2025, the sheeting and beading had disappeared (5.5 months). I reapplied this 5/7/2025. Final verdict: I'm going to finish this product and move on. At best, with my conditions, I'd expect 3-6 months. The beading seems to wear off in 3 months. Next: I'm going to try ONR, and LSP w/ Gyeon's Can Coat Evo or Gtechniq's C2V3 ceramic sealant.

It’s excellent product to layer on as an LSP for frequently washes cars or daily drivers. Makes cleaning the car much easier. Works on windows, plastic trim and headlights. Stops bird crap etching or at least makes it easy to remove if you catch it quickly. But remember bird stuff is acidic so no coating will stop etching completely. Highly recommend graphene ceramic. Lasts 3-5 years. This will last 3 months but regular usage you will see hydrophobic last 8-12 months continually.

石油っぽい臭いが残念 艶と耐久性と傷消し効果は最高。

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

パール車に効く。めちゃくちゃいい。ギラギラするし施工が塗るだけで簡単。伸びる。 ただ、拭き取るのに結構時間がかかるけど手で施工出来るレベルだし使い勝手がいい。

after seeing all the hype on the market about graphene being level par with ceramic i had to give this a try, application is extremely easy, shake the bottle, prime the pad with a couple sprays and it'll do 1 half of a bonnet or roof with ease. allowing the product to flash off after 20-30 seconds and then wiping down is extremely painless as product just comes straight off. my only issue with this product is that it states that it will last 12 months, however 6-7 months down the line and i can already see the product starting to fail in areas resulting in me having to top up with a ceramic shampoo to keep some hydrophobicity to the vehicle bodywork, i'd be willing to give the product another shot just incase i've received a bodge bottle.
