I had some belts that separated at the glue joint. Had them for a while, put them on the sander, they popped immediately. Decided to give Red Label a try. Tested a belt on a saw-horse joint, held up, did good, I'm happy. Expect to use on a large cutting board within a few days. If that works out as well as I expect, will buy a pack of a courser grit. Wood working is just a hobby for me. This SKIL sander is close to 80 years old, was my father's, glad to have it operating again.
