Collinite 845 is the durability king of this group, a 1936-vintage carnauba-polymer wax that detailing forums trust for four-plus months of protection through salt and sun. Applied thin, it is easy to use and machine-friendly; it trades a little show-car warmth for protection nothing else here matches.
- — Exceptional durability, commonly reported at four to seven months of protection
- — Carnauba-polymer blend holds up through winter road salt and summer heat
- — Liquid formula is easy to wipe on and off, and is machine-friendly
- — Must be applied extremely thin or it becomes hard to buff off
- — Shine is durable and reflective but less wet looking than a show carnauba
- — Old-school formula benefits from a fully decontaminated surface first
