303 Graphene Nano Spray Coating is a Graphene Oxide-based coating, that will provide a high level of protection for 12 months. This product also reduces the temperature of the surface its applied to, in turn reducing the amount of hard water spots on your cars paint. It also features substantial hydrophobic properties, that helps water shedding and reduces build-up of contaminants. After application, the paint will exhibit enhanced gloss and clarity too. The main difference between this product and others in the market is the combined durability and protection, along with how simple and easy it is to use. It bonds to the surface without prior paint correction or decontamination and is difficult to apply incorrectly. Sprayed it on and let it sit too long, or missed a spot when buffing it off? No problems, just come back and buff the remaining product off. No need for machine correction of high spots. It can also be applied in direct sunlight as the heat helps the product cure faster. It can be used on a range of surfaces including paint, glass, wheels, trim, and more!

This has to be the easiest product ever to apply. The main thing is to follow directions and make sure that you do the recommended paint correction steps first if required. The shine is very good and the water is sheeting off nicely. As for the durability of the coating, ask me in 12 months time. This stuff is supposed to be a step up from the ceramic coatings, but we shall see. The tests done so far by other testers are promising...

Bought this product from the staff's recommendation. This thing is insanely good and versatile as stated by the product itself.Use on paint, glass, trims, etc.Use it on your bathroom shower glass, your windows.Forget your Rain-X, chuck that thing away. This one got it all covered.The price is expensive, but considering it replaces all other products for your car. It actually saves you money.

If applied as recommended provides excellent water repellent qualities. I may be mistaken but does appear to keep the car cooler when parked in the hot son. This makes it superior to ceramic products for example which tend to heat up - causing plant material such as pollen to melt - which if parked outside in the Australian summer seems to create a fine film of sticky hard to remove crap on the car within hours of polishing. The other thing I like is that not much is required and there is not much residue once buffed. Definitely the best type of protective product I’ve come across - very good value .

Have always been mega suspicious of car coating offered by dealers at vast expense . Bought this as have new car and decided to give it a go. Absolutely amazed at ease of application and soft polishing. Really good results. So good I tried it on duco of my ancient car ! Looks fantastic.
The product applies easily and is everything it states on the bottle easy to apply with an amazing mirror finish Did not have the 'slip` smoothness but was not a concern. 1 coat applied before this review I found it repels dust on alloy wheels. The car cleaned easily with a light hose. Warning - Black porous plastic is a no go zone as it is very difficult to remove. Used on widows and windscreen with very effective results in the rain
My car is one year old new so I washed, clay bared and prepped with CMX. After rinsing that off and drying my cars clear cloat was butt naked. 303 goes on really, really quickly. I did the criss cross pattern and it buffed it off with microfibre. It doesn't have that super silky feeling like waxeds do, but it leaves a wicked shiny coating. Did all the glass and trims, no white residue like waxes leave. Did the rims too, but ai sprayed directly onto the wheels to give it a thick coat. Washeds it yesterday for the first time. Didnt even have to break out the mitt, the preswsure washer just blew everything away, even the OEM volkswagen brake pad dust came off with water. Its amazing how far a couple of squirts of the bottle onto the pad goes. You use hardly any product ... MoreMy car is one year old new so I washed, clay bared and prepped with CMX.

Its amazing how far a couple of squirts of the bottle onto the pad goes. You use hardly any product to do a large 4x4. One week later Im glad I used it.
DO NOT USE ON POROUS PLASTIC TRIM as it will discolour it (must be solvent based), but smooth plastics seem ok. The product applies easily and has excellent hydrophic properties - and does keep the dust off my paintwork nicely after several coats. Doesn't have the 'slip test' smoothness which was a concern but actually i think it adds to its ability to repel dust - especially on alloy wheels. After a light offroad test, the car cleaned easily with a light hose.
Honestly this stuff is awesome, washed the car, used a Mothers Speed Clay 2 to remove the contamination from the paintwork then dried the car. Used the 303, so easy to remove and the results were so good I had to do the wife’s car too. Large 4x4 and small sedan and still have 1/2 bottle leftover. Highly recommended!
easy product to use. Done it in the middle of the day set very quickly, easy to buff. Used a foam application pad to apply to the car. did it in small sections and like I was told less is more. UV protection applied to plastic bits. Swear by 303 been using them for over 9 yrs great products.
easy to apply but can smear when removed. this just requires another wipe with a clean microfibre. Used it on black paint, gloss and shine were a bit ordinary.....but sheets water easily so less water spotting, which is the main reason i use it. Turtle Flex graphene spray is harder to remove, has more gloss but less sheeting.
