303 Products Graphene Nano Spray Coating - Enhanced Gloss Finish & Depth, Water Repellent Spray, UV Resistant, Helps Prevent Scratches, Beyond Ceramic Coating for Cars, Car Detailing Spray, 24oz.

I put this on my velvet maroon Grand Cherokee about one year ago, and after about one year and a New Hampshire winter it still beads quite well. It seemed to repel most dirt even through the winter. I have been thru the touch less wash 25 times and while no there is no substitute for a hand wash occasionally (especially for a daily driver) but it really works well. I only did one application which is great. It's not perfect, but no car sealant is. Certainly a great value for the money.

Easy to apply and lasts a very long time. I find it vest to apply in the shade as letting the haze dry in the sun makes it very hard to buff off to finish. Goes a long way

Great Graphene Nano Spray to protect your vehicle's paint. Repels water, acid rain and keeps bugs from sticking to bad to your front grill and hood areas. Can be used on glass, plastic molding around your vehicle and wheels for durable protection. I've used them all and this is above Ceramic Spray Wax. This is my second bottle in 4 years. I've only had one issue, spray nozzle gets clogged, stops spraying after 8 to 12 months of initial use. Company is aware of the issue and has agreed to replace with a new nozzle after 21 months since purchase. I'm going to try and rinse spray nozzle with clean water after each use to se25e if that helps. 3/14/25

303 make some good products and I'd buy any of them.

Applied to camper and 6 months later it's still beading up great after sitting in Florida sun

I'm genuinely impressed with 303 graphed wax because it delivers a deep gloss and make my cars paint pop witha shiny glow

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.

303 Graphene spray works great, easy to apply and wipe off, do not let it sit on your cars paint for more than a few minutes as it will be hard to wipe off if left on to long. Definitely recommend this product.
