US Chemical & Plastics (USC): A Legacy of Collision Repair Innovation

When collision repair professionals reach for the products that define their craft, they often find the name U.S. Chemical & Plastics — better known as USC — on the label. With more than five decades of experience formulating and manufacturing repair and refinishing products, USC has earned a reputation as one of the most trusted names in the body shop industry. In fact, USC is widely credited as the first body filler manufacturer in the United States, and that pioneering spirit continues to drive their product development today.

A Complete Collision Repair Lineup

USC's catalog is built around the full arc of a collision repair job, from structural rebuilding through final surface prep. Their flagship category is body filler, where they offer a broad portfolio of premium and lightweight options engineered for consistent, professional-grade results. All of USC's body fillers are designed to be stain resistant, clog-free, self-leveling, and formulated with superior adhesion properties — making them equally at home in a high-volume collision center or a weekend restoration garage.

For damage that goes beyond surface dents — rust-outs, holes, tears, and structural cracks — USC's line of fiberglass resin products steps in. These heavy-duty resins are engineered for versatility, performing on metal, wood, gel coat, and fiberglass substrates alike, across automotive, marine, industrial, and household repair applications.

Of course, every great repair job depends on great surface preparation, which is why USC rounds out its lineup with a full range of sanding discs. Their Gold Pro® abrasive line is particularly well regarded in the trade — featuring multi-layer construction with resin-over-resin bonded grains, a special anti-clog coating, and durable latex paper backing suitable for both wet and dry sanding. For shops demanding even higher performance, USC's Purple Premium film-backed abrasives represent the next evolution, with optimized grain technology and a proprietary vacuum hole pattern designed to run cooler and last longer.

Whether tackling a small dent repair or a full panel restoration, USC provides the right product for every stage of the process.
