The right way to do it is to take a grinder with a 36 grit disc and grind all the dents. Its alot easier to see the dents when theres paint on the car. Then after its blasted, you can see the grind marks where the dents are.

Most normal sandblasting shops dont do body panels. You will need to find a shop that specializes in paint stripping. The shop I use, uses plastic media.

Stripping just the outside can be done with the glass in the car. You just want to make sure its covered good.
