Review: 303 Graphene Nano Spray Coating

New member here. Great review. A question:
Is there any advantage in letting a coating of the 303 Graphene cure for 24 hours and applying another layer, or is one coat all that is needed ?
Thank you

Two coats on the horizontals should give you better protection.

In general (I haven’t tried this 303 product) - I always like 2 coats to ensure everything gets touched. And I always feel the results are better after two coats.
 
I can’t remember reading if applying over a car pro ceramic coating is a thing ? Will it adhere ?

That is actually one of my issues with 303 Graphene is that it is advertised as being able to work over just about any coating, wax, or sealant. I am somewhat skeptical that it can work over any coating but I’m hopeful.
 
Way back a few pages I did an A/B test comparison between the graphene 303 and blackfire si02 spray. …It’s now been seven weeks in the weather but I don’t need to take any pictures , they are both beading fine, I can tell absolutely no difference between the two. Both work well.
 
I just took my new car to a touchless car wash, brought it home, dried it , used my cordless orbital with a black pad to apply a coat of graphene on every surface of the car (except the glass) in about 50 minutes. It was so easy, I love the stuff because you can see exactly where it is so you don’t miss spots, and if you wipe off one panel at a time it comes off very easy.… This is my go to product until there’s a new breakthrough… The gloss is outstanding, and the overall product is cheap and goes a long way.

Only downside is the sprayer is lousy and leaked after the second major use,, so I transferred it to a prima bottle with a good spray head.
 
I bought two bottles of the 303 Graphene Nano Spray. I haven't had a chance to use any yet. I read that there was a bad batch. Anyone hear about that. Did anyone get a bottle of the bad mix. Does anyone know what the bad batch code was? I heard that 303 wasn't very cooperative in acknowledging the error. The bad stuff was noted several times in youtube durability tests. Phil

I suspect they are slow to respond because they don't want to be, or unprepared, of all the people who will want new bottles because of the bad batch. I was not impressed with their product and maybe my bottle is part of the bad batch.
 
The product has a rebate and their rebate page doesn't accept that product. That's a huge customer service fail.
 
Well, I opened a bottle and used it on a buddy's 2021 White Cab 911. Used the Rupes "Full Size" and the Flex 3401. Polished out the paint and then applied the 303 Graphene. Super easy to apply. Doesn't smell too much. I forgot to use gloves and mask, but did apply in an open garage. Car came out incredibly well. I look forward to seeing it in the daylight, once the Graphene has cured. Stay tuned.View attachment 72839

I agree definitely the black applicator if doing by hand.


on my griots 5 in orbital, I apply with a black soft wax applicator pad, (easier on my old shoulders).....LOL

I'm confused, you apply with a black application pad (by hand) and what do you do with the Griot?
 
Bad punctuation.......If I was using a hand applicator I would want it to be black, I use a black orbital pad on a griots cordless orbital. I’m just saying if you got to do it by hand make sure your applicator black, especially if your OCD… LOL

Punctuation corrected above
