Review on 3M Orbital Sander Air Powered Self Generated by Mario Beaklini

In my job (painter in an auto repair shop) sand scratches will reappear after a day or two if the primer/coat/clearcoat soaks in uncomfortably to say the least. Normally you would see scratches right now, but after buying one of these and customizing them to my needs, it blocks just as well, faster and smoother than manual blocking, which is barely noticeable when the material pulls in. Great tool!
