Buffing cones for plastic/laminations

Buffing cones for plastic/laminations

1)Which brands of buffing cones have you found to hold up the best for
buffing each of the following: polypropylene, acrylic laminations,
epoxy/carbon laminations. Where do you get them and what do they cost?

2)Granted, proper technique is vital to prolonging their useful life, but
there always seems to be some abuse (development of grooves) by certain
people. Other than giving everyone free rein and buying as many replacement
cones as people go through, how do you get cone users to take responsibility
for not ruining them? Do you have any policies in force at your facility to
address this?
