adb2f the sander is pretty strong it seems to keep the same rpm even if you push very hard on it (lots of torque due to electric motor) it would be hard to do the underside of your car because the actual unit is large, and it's somewhat heavy when your upsidedown
when i stripped my car to bare metal, i used a chemical stripper (aircraft remover) and then sanded the remaining black primer stuff that the stripper didnt take off. however i stripped my fenders by just sanding ( i think i used 36-40 grit followed by 80) it worked fine, was less messy but took longer because i had many coats of laquer paint on my car, and man is that stuff hard. if you only have 1-2 paint jobs on your car it is very resonable to just sand off the finish
plus when your done with sanding you can buff out chrome and your paint after you get that well deserved paint job
