I was nervous about the 3M Eraser wheel at first, but if you run your corded drill under 3000 rpms and just touch the wheel to the panel and let the wheel do the work. I didn't apply any force that wasn't needed other than to hold it up against the body. It will leave a white sticky residue ( it did on me) that came right off with WD40 and a cloth. Watch some Youtube videos and watch those guys. After I removed all the glue and rubber residue, I put a foam pad in my drill and some polishing compound and finished it out. Can't even tell anything was there.
