For more difficult material the leather will probably get warm to the touch before you finally get the "flow" finish.5) After quite a bit of use this method may stop working. Your polishing paste may have crystallized in which case the old paste will need to be completely washed off of the leather. You may also need to roughen up the leather surface again; go over the whole surface with diamond cutting wheel to accomplish this. I use a dust mask and a vacuum cleaner to avoid inhaling the dust. - For a final "water" finish, try 14,000 diamond mesh with a little light oil on a wood disk, also turned very slow. - Surefire can't fail but expensive method no. 2. - Do the best you can with any other method then finish up with a 3,000 grit diamond resin bond wheel. Hit it with a light spray and let it go dry. As it dries you will feel it drag just a bit, that's when it is putting a flow polish on it. Only If absolutely necessary apply much pressure, you will get a nice finish with even soft material. The draw back is this goes against the manufactures recommendation to always use with water, so there is a danger you eventually gum up the wheel to where it doesn't work anymore. If you gum up the wheel I have found it is possible to restore it. Hold a piece of a silicon carbide grinding wheel against it while it is running wet. This will remove the resin that is now covering the diamonds. In my experience it won't hurt it and will make it usable once again, although it won't be quite as good as brand new. Additional hint- use purified bottled water, not tap water. Tap water has mineral content that will crystalize under heat and pressure forming a grit, making polishing jade very difficult. Polishing became much easier for me once I found this out.
