There is a bit of hype around this product.
Was waiting for a decent price.
Some members got a targeted $10 store credit (if combined brings price down to $29)

Product Info
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 it’s applied to,
in turn reducing the amount of hard water spots on your car’s 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.
Spec on Vendor Website
Works on glass too as water-repellant agent.
And claims to reduce heat absorption applied to surface.
$35 at Autobarn if you don't have the credit.
