Great Addition to the 3M Sanding Sponge Lineup


from Cerritos, CA, United States

Comments about 3M 120 Grit Sanding Sponge (20908-120-UFS):

I absolutely love 3M sanding sponges and have been using them for decades - perhaps even since they were first introduced to the retail market. They're effective, long-lasting, and reasonably-priced. However, the grooved channels on one side of the pad have effectively solved a problem that has long-plagued finish sanding, whether traditional sandpaper or sponge - loading of the grit surface with residue that winds up scratching the very surface you're trying to smooth.

Although listed as 220 grit, the sanding surface seems to be rougher, but the results indeed seem consistent with 200 grit sandpaper. Lightly sanding a brushed polyurethane coating that had already been sanded with an electric pad sander, the 3M flexible sanding sponge effectively channels the dust to the outside, leaving behind a smooth, matte surface that is ready for the next coat or a final polish with a finer grit or steel wool.

Comments about 3M 120 Grit Sanding Sponge (20908-120-UFS):

I received this sample product and initially had my doubts. But, these little sponges are great. They are small enough to get into tough areas to sand and they are pretty durable. I will definitely be purchasing more of these soon.
