Picking up my 58 plate brilliant black s line next week. Must admit i've never taken care of my car before, so what products do i need to get? From what i've been reading i need shampoo, some sort of wax, and possibly a sealant of some kind to use before winter? The paintwork is in very good condition and i want to keep it that way, so all advice would be welcome, especially from other owners of this colour!
