It looks like Adams is coming out with one. Has anyone had any experience applying a graphene coating? How does it hold up? Does it really perform better than ceramic vs. water spots?

graphene in any application you're going to be doing outside of a lab that grows it on the object directly, fractures.

So while initial application may be not too bad, any kind of pressure (like anything equivilent to the pressure of the weight of a ping pong ball) will cause it to crack. I'd imagine the cracks would not be too great at doing the things graphene does. I'd imagine it would have longevity problems more so than ceramic/quartz.

Graphene's high resistivity can make for durable coatings that do not crack and are resistant to water and oil; its excellent electrical and thermal conductivity can be used to make various conductive paints, and a strong barrier effect can contribute to extraordinary anti-oxidant, scratch-resistant and anti-UVA coatings.

It'll probably be graphene in a regular wax base, but it has the potential to make the wax last much longer, could be a wax that lasts a year or so. Si sealers work so well it's hard to imagine better, but they only last a couple months or so.

graphene that isn't lab grown on the surface directly is not the same as graphene that is deposited on the surface using existing flakes of graphene. The latter being the kind that you'd get from a spray or most non-laboratory settings. That graphene is prone to cracking under the smallest of stresses. You always hear about the strength and abilities of the laboratory grown graphene where you're dealing with a single atomically bonded sheet of pure graphene. That's not what you're getting here.

Now granted, cars dont flex too much, but the body panels flex enough that this graphene will likely not be able to resist cracking. That would probably show as a breakdown of the hydrophobic properties over time. But at the thickness needed to remain mostly transparent, it's hardness is not going to offer much if any protection as it's not strongly bonded to itself and anything dragging against it will likely remove the coating at the contact point even if it doesn't scratch thru it directly.

This kind of graphene is the kind you're used to having in lubricants...and functions best as a sacrificial barrier that is able to move around with friction contact.

I'd also imagine that the graphene is not really bonded to the paint, but just resting on it after being rubbed in. So cleaning the car will likely remove what you've deposited on the surface ...as would subsequent buffings etc.
