Finding high-quality, durable sanding sheets for “papering” rocks has been quite an issue. The market is dominated by 3M and Norton, and while their products are quite adequate, I have been searching for better quality product, preferably made in the USA. I can now say I have found such a product!
We now exclusively stock premium J-weight Aluminum Oxide 9 x 11 sheets in 3 grit sizes – 60, 80, and 100. These are stiffer than paper-backed sheets, but these cloth sheets have the perfect amount of flexibility, ensuring they lay flat on a sanding jig. They also provide excellent cutting and long life. In my own testing, I have found that you can use each sheet up to 4 times *, minimizing your cost over time.
* - Each sanding sheet should be used a single time – 1 sanding sheet for each rock in a particular sanding session. However, these sanding sheets can be used 3 or 4 times in successive sanding sessions. The first time the sheets would be brand new (so one brand new sheet for each rock), the second time they would have minimal wear (one slightly used sheet for each rock), the third time a little more wear (one moderately used sheet for each rock), and the fourth time even more wear (one end-of-life sheet for each rock).
