Review on 3M 2604 Softback Sanding Sponge by Todd Phillips

This product could be great. The idea is amazing. The foam makes it a lot easier to get into corners or sandy turns, and it feels better on your hands/fingers. If only they knew how to make sandpaper stick better. The tiny "grain" rubs off so easily you can see it on your piece right away. A few passes is all it takes before you have to use another sheet of paper. I bought it for sanding between wood surfaces and it's great for that, but if only it held up better I'd use it for everything and never go back to "paper".
