Is 476 more durable than 845? Collinite has been my go-to for the winter protection for the past few years. If there is a sealant that goes on as easy and has better durability than Collinite let me know what it is. My current go-to sealants are both real easy to apply and buff off....Optimum Opti-Seal & CarPro Reload. The Opti-Seal flashes off on it's own so I don't even need to buff it off. The Reload you wipe off while it's still wet....doing small sections at a time. Neither of them have the durability of Collinite 845 though.
