C4 Permanent Trim Restorer

Gtechniq C4 is a permanent trim restorer that restores faded, dried-out plastic and rubber trim to a deep, rich matte-black finish. Unlike dressings that wash away, C4 bonds to the trim surface using a unique silicone-free formula, providing durable protection that lasts months per application. Ideal for bumpers, door trim, underhood plastics, and rubber seals.
