I'm thinking of purchasing a 12 inch disk sander and would like to convert it to H & L. I've always had problems in the past with PSA paper not coming completely off and then having to scrape off the remains. H & L works great on all my small RO sanders but I don't know if there would be any issues with it on a larger surface like a 12 inch disk. I know you can buy 12 inch H & L disks but they don't seem to be too common of an item. Anybody have any experience with this?
