Some cars have life time factory wax based rust proof on several hidden areas. The owners manual, in case of my 1992 MB, recommends against after market rust proof due to compatibility problem (after market rust proof may remove factory wax based rust proof).
Turtle Wax Liquid Clay Bar contains chemical cleaners to dissolve road grime and wax. This runny fluid will flow into the door (rain drops also go into the inside of the door even with the window closed) and many hidden areas during application and rinsing.
