I wax my car with Zymol (smells like banana cream pie now!) and now that it is winter would a detailing wax every few days after a wash to remove salt extend the life of the wax? Would a spray wax be better then a detailing wax? I normally use Zymol BMW and Griots products. A specific recommendation from another north salty car driver would be great! Thanks for any help Damien PS what is that smell of a BMW after you buy it? Used specific! Is that one of those scented BMW interior cleaners?
