A few seasons ago I was visiting a family member at their house for the week. I offered to clean their car if they had any supplies. They had Blue Coral Car wash, Nu Finish, Mothers Pure Carnuba, and a few terry towels. Lets just say, their Cadillac Caterra looked sooo much better with simple mediocre products such as Nu Finish followed by Mothers Pure carnuba... In that situation, it did the best it could....
