Seymour Duramix™ Automotive Rigid Plastic Repair Material Product Details

Seymour Duramix™ Automotive Rigid Plastic Repair Material is a two-component repair material and adhesive for professional work on rigid and semi-rigid parts. It bonds, rebuilds, sands cleanly, and featheredges easily on properly prepared substrates, including SMC, TPO, rigid plastic bumper covers, fiberglass, steel, and aluminum.
