Product Review (submitted on January 25, 2010):

Excellent sanding block for doing rough & finish work, can use peel & stick sandpaper, or regular sheets of sandpaper (works best with whole sheets).

I have used them for rough sanding through finish sanding of primer & body fillers, and they perform great. Very stiff block, for flat surfaces, but has enough flexibility to sand small curves curves & flat panels. Excellent addition to the smaller Dura Block sanding blocks.
