The 1965 Mustang Fastback gets waterless washes only. No hose, no buckets, no risk of water creeping into rust-prone seams. That means the wax needs to be slick enough that a damp microfiber doesn't grab and marr 60-year-old paint. Ethos Ceramic Wax delivered that slickness for six months without the full-day prep work a true ceramic coating demands. Application took 20 minutes in the garage. Water beaded tight and rolled off body lines like we'd spent a weekend with Gtechniq or CarPro. Then winter came.
