We stock a variety of long-wearing abrasives, each formulated to obtain a desired finish. Generally, the higher the grit number, the finer the abrasive. The finer the abrasive, the smoother the finish. Coarse-grit abrasives cut fast, but the finish isn’t quite as smooth as with fine-grit abrasives. Experiment with each to discover which works best for your application. Most Skat Blast Abrasives are “Made in USA” and all are “virgin” material, which means they have not been processed or reused.
