It seems to me you use it with the soft pad on all of the car provided the body is perfect & there isn't any major repairs. And the flat hard pad on rare flat areas. So it just follows the body & gives a perfect sand.

Basically if you wanted to put a car in primer that had a good body & give small filler to nicks & dents etc. Can the Dynabrade do it all? If not, what else is usually done?

thanks.
