Here at Abrasive Resource, we sell sleeve after sleeve of waterproof silicon carbide paper. It's used in almost all of our markets--automotive & marine, cultured marble, woodworking, metalworking, stone, glass, plastic and even rubber!
The history behind this versatile abrasive is an interesting one. A man named Francis Okie, a printing ink manufacturer in Philadelphia, had an idea for a new type of waterproof sandpaper. Okie's idea was for a revolutionary new sandpaper that could be used with water or oil. Wet abrading would reduce the dust hazards created from some of the dry sanding applications and also create a smoother finish.
Francis was so confident of the cutting power of his wet or dry sandpaper, he supposedly kept a piece of it in his club locker and shaved with it before golfing!
In 1921 the 3M Company purchased the rights to waterproof sandpaper from Mr. Okie for $1.00.
