3M used to make a material called 'Butter Cut', a self-adhesive masking
material intended as a sandblasting restist for stone, but it worked great

withstood silica or aluminum oxide at 70 lbs. of presure with no problem.
Your local tomb-stone supplier probably uses it unless they've gone over to
some computerized device.
