High-Quality Sheets for Low-Pressure Applications
Featuring our best abrasive for wet sanding, 3M Wetordry Abrasive Sheet 434Q is designed for delicate collision repair jobs requiring the most refined sanding patterns. Synthetic silicon carbide mineral abrasive is very sharp and requires only light pressure to provide a final quality finish. It is built on durable C-weight paper backing that resists curling and holds up during wet or dry sanding. Sheets can be easily cut to size for hand files and blocks or for machine sanding applications.
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.
For the Lighter Side of Collision Repair
Our 3M Wetordry Abrasive Sheet 434Q may be used for light sanding on fully cured clear coat and refinish acrylic lacquer, and for leveling minor dust nibs, adjusting mismatched orange peel or removing paint runs on all automotive paints. It is also suitable for achieving a finished quality on dark-colored automotive paint where compounding is difficult.
