3M SANDING SPONGE ASSRT! FOR PMC! METAL! POLYMER! &MORE

THESE ARE MY SECOND FAVORITE SANDING MATERAIL FOR MY METAL AND PMC CLAY.  THEY ALSO WORK GREAT ON OTHER MATERAILS. 

WHEN CONSIDERING PRICE PLEASE TAKE INTO CONSIDERATION THAT I SHIP FOR FREE.  THESE PADS MEASURE APPOX. 2 1/4" X 2 1/2".  THE SIZE IS GREAT FOR PRECIOUS METAL CLAY AND LETS MY STUDENTS BE ABLE TO AFFORD A FULL SET OF THE DIFFERENT GRITS.   BACKED WITH A WATERPROOF COATING OF ALUMINUM OXIDE IN THE FOLLOWING GRITS:

#1. MEDIUM       120-180 GRIT

#2. FINE               320-400 GRIT

#3. SUPER FINE 500-600 GRIT

#4. ULTRA FINE 800-1000 GRIT

#5. MIRROR FINE 1200-1500GRIT

I MAINLY USE THESE PADS TO POLISH PMC IN ITS GREENWARE STATE (THAT'S WHEN YOUR CLAY IS IN AN AIR-DRIED STATE AND LEATHER HARD).  IF YOU START WITH THE MEDIUM GRIT AND GO THROUGH ALL THE GRITS YOUR PIECE WILL COME OUT OF THE KILN READY TO BE TUMBLED AND PRODUCE A MIRROR FINISH.

BESIDES PRECIOUS METAL CLAY, THESE PADS ARE USEFUL WHEN SANDING METAL, WOOD, PAINT, PLASTIC,CERAMIC CLAY, POLYMER CLAY AND EVEN DRYWALL!

I ESPECIALLY LIKE TO USE IT AFTER I HAVE APPLIED A PATINA.  THE SPONGE IS FIRM ENOUGH TO LIGHTLY SAND OVER MY PATINA PIECE AND HIGHLIGHT THE HIGH SPOTS WHILE STILL KEEPING THE NICE DARK CREVICES AND LOW AREAS UNDISTURBED.

YOU CAN USE THEM OVER AND OVER AGAIN, RINSING WITH PLAIN WATER!

USE A STIFF BRUSH OR TOOTHBRUSH TO RECLAIM YOUR PRECIOUS METALS.

THESE PADS ARE FIRM AND FLEXIBLE, BUT NOT AS FLEXIBLE AS MY 3M SANDING PAPERS WHICH CAN ACTUALLY BE FOLDED TO SAND REALLY TIGHT SPOTS.  CHECK THEM OUT TOO IN MY EBAY STORE AT WWW.YourCosmicCreations.com .
