I got it for my car. It's called AutoGlym LifeShine. The service crew at the dealer apply the sealant to the interior and exterior, and you get a fetching green and red holdall containing several products: bodywork shampoo, interior shampoo, resin polish, glass polish, screenwash, gloss protection, wheel cleaner, vinyl and rubber care

, a sponge, a fake leather dryer, a pack of cotton polishing cloths, and a manual explaining how to use it all.
I'm not convinced it's worth it for the carry-home kit, as you need to invest time and effort, but I persuaded myself that it was better for the car to have the sealant applied than not.
