The Eraser worked as advertised. I had large body side stripes on each side of a '95 Nissan pickup and I had worked on several occasions with a heat gun to get only a little off at a time. Finally I got so tired of burned fingers I just left a huge portion of it. I put the Eraser in the drill and 20 minutes later it was all gone. The striping was applied when it was new, on top of clear coat. On one of my fenders I had the drill running at high rpms and I did get some heat discoloration to the clear top coat. Of course the paint is 22 years old and it doesn't matter. Instructions come with the eraser so keep the drill rpms medium to low, take your time and be ready to clean the adhesive off with some specialized cleanser.
