POLISHING WITH THE LEATHER BUFF PAD
For final polished gemstone results, place the 6" cowhide leather pad (rough side out) on the foam
polishing end disc using the 3M On/Off adhesive cement (red box) to hold the leather pad securely
while buffing the gemstone in a rocking motion (Figs 22 & 23). Only use a small amount (8 to 10
dabs) of 3M On/Off adhesive cement on the smooth cowhide surface, smearing it uniformly before
placing it over the foam rubber on the polishing disc. When the final polish finish of your gemstone
has been achieved, remove the leather disc and place it in a zip-lock bag to protect it for future use.
It is not necessary to use any polishing media or liquid (water) when buffing the gemstone with the
leather disc. Be sure to firmly grip the gemstone by hand or with a dop-stick (wood dowel or aluminum
rod) cemented or epoxied to the back of the gemstone while using the leather buff pad.
