Auto body repair & detailing: sanding, orbital sander, bare metal

Question
i am trying to sand a car ,can i use a vibrating sander? and also what grit of paper?

Answer
it depend on what level you want to tke the vehicle down to, primer? bare metal? is there rust? Usually start with 80 grit and then use 180 before you primer the car to repaint. I don't quite understand what a vibrating sander is. Usually a orbital sander is what is used.
