  • Our take on the 20H Nano Graphene Ceramic Coating for Cars, 70ml

    A 70ml graphene-infused ceramic coating kit from DRONAR, sold as a DIY paint protectant for cars. It claims 20H hardness and a 10+ year lifespan, which puts it in the same class as professional-grade coatings that usually need a trained installer. The graphene additive is marketed for slickness and water beading, but real-world durability depends heavily on surface prep and curing conditions. It suits confident DIY detailers with a garage and time to prep; most casual owners will get better results from a simpler spray sealant.

    Pros
    • Graphene additive boosts slickness and water beading
    • 70ml covers a full mid-size car with some left over
    • Transparent formula works on any paint color
    • Can be layered over cured coatings for extra gloss
    • Applies by hand with a applicator and buffs off like a wax
    Cons
    • 10+ year and 20H claims are marketing, not measured durability
    • Needs full decontamination and polish first or it bonds poorly
    • High spots and streaks are easy to leave if you buff unevenly
    • Curing takes days away from rain and washing
    • Small 70ml bottle leaves little margin for a large SUV or van

    Questions and answers

    Is 20H hardness real?
    No independent test backs a 20H pencil-hardness rating on car paint. Treat it as a marketing label; the coating does add a slick, sacrificial layer but will still mar from grit and bad washing.
    How long does it actually last?
    The 10+ year claim assumes perfect prep, indoor curing and careful maintenance. Realistically expect a few years of visible beading on a daily-driven car, less on a neglected finish.
    Can I apply it over wax or an old coating?
    No. It bonds to bare, clean paint. Strip wax, clay, and ideally polish before applying, or it will sit on top and fail early.
    How much does 70ml cover?
    Enough for one mid-size car or a small SUV with a little spare. Large SUVs, vans and trucks may need a second bottle, especially if you coat wheels and glass.
    How long before it can get wet?
    Keep it dry for at least 24 hours and avoid washing for about a week. Full cure takes longer in cool or humid conditions.
    Does it work on glass, wheels and trim?
    Yes, it can be used on glass, wheels and plastic trim, and it helps shed water and brake dust. Avoid textured plastics where residue can dry white.
    Where is the 20H Nano Graphene Ceramic Coating for Cars, 70ml cheapest?
    At Amazon, for $23.98, 63% under what the other stores charge, as of our latest check.
    Where can I buy the 20H Nano Graphene Ceramic Coating for Cars, 70ml?
