I just got a Jet 16/32 sander and the paper was getting clogged up in sections and burning the wood, I have a dust collector and use the eraser regularly. I saw a tip in one of the magazines I get on getting stubborn material off the paper. I tried it and it worked great. They used a piece of plexiglass, holding it on the area while it's running (like the eraser), moving it back and forth. It took a little while but it really worked, this little trick will save me from having to replace the paper when it gets a bad spot. :thumbs_up
