Silicon Carbide — Sharp Abrasive with a Refined Touch

Abrasive Sheet 434Q features silicon carbide — a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep, smoothing of clear coats and as an alternative to compounding. While it breaks down faster than aluminum oxide, silicon carbide produces a superior finish. Users only need to apply light pressure to obtain a consistent scratch pattern desirable for final finishing.
