Query: didn't work

This product did not work for me, to repair a scratched disk. I believe the tube I was sent was way too old, "expired"... The substance seemed very liquidy and not "paste" like... The bottle was 1/2 empty... so I don't know if it somehow evaporated over the years, or that's just how it is... It may work for others but it certainly did not repair the few disks I had that were scratched, from lightly to severely... toothpaste worked
