Need some input!

I do mobil paint-touch up for car dealerships. Primarily I just do minor scratches and rock chips. Is there an electric hand held sander that I could use for wetsanding scratches in the clearcoat. Also is there a drill that someone recommends that I could use to buff out the wetsand marks. Typically when I use my high speed DeWalt buffer I run under a 1000 rpm. I need something high in volts but not too heavy to lug around. I go from car to car on the lot and really never have to move the cars to preform work. I'm trying to be efficient. Thanks for the help, Michael
