We work in an upscale shop making Porsches and Audis, 90% of our work. I have two other DA grinders (Hutchins & Snap-On) quitting DA which I sue the most. When it comes to cutting and stripping bumpers and hoods, this beast gets the job done much faster. If we sand the bumper with finish sanders it takes 1.5-2 hours and in this case it takes 30 maximum. Worth the price!. I plan to use this to take apart my 72 Nova.
