Nano Coating

Nano coatings are marketing-speak for any sealant claiming nano-scale particles that bond to paint, glass, or wheels for hydrophobic protection — the term covers everything from light spray sealants to legitimate ceramic coatings. Read the actual chemistry (SiO2 percentage, claimed durability, application method) before buying, because "nano" alone tells you very little. Use them where you want easy water shedding without committing to a full ceramic install; pair with a pH-neutral shampoo to keep the surface energy intact.
