i want to paint some parts on the car and have been curious about sanders. you hear all the time about d.a.'s and wet sanding, is there any electric sander i can use when doing the prep work and like 400 grit? i dont mind wet sanding the final product by hand, getting out orange peel and whatnot, but i would love it if i could make the prep easier. i just dont think my little 3 gallon compressor would survive with a d.a.
