Rated 5 out of 5 by from Anything 3M Makes Is Top Shelf One day in the late 70s or early 80s, a 3M rep handed me a small bottle filled with glass microsphere bubbles, the "latest and greatest fill material for resins ever", he said. He also told me when they were developing the bubbles, some of them came out solid. In attempting to find out how to get rid of these "mistakes", they learned how to make them. Solid glass spheres are why signs and road markings glow so brightly when your headlights shine on them. I experimented with the bubbles he gave me and discovered the ones at the surface would break if the part was sanded or tooled. A Perfect way to hold stains on dye resistant resins. Great product, great company and great ideas.
