Keystone’s recycling process begins with thermal reforming. High temperature soak tanks are used to soften the bumper and chemically clean the bumper, returning it to its originally molded shape. Each bumper is then stripped to insure good paint adhesion.

Now the bumper is ready for our repair technician. Each person performs the complete repair process and follows the bumper up to its final prime coat. Double sided airless plastic welding is the primary method of repair. First the technician tapes and glues the torn area, holding them secure. Next, The technician uses a die grinder to cut a grove so the plastic welding rod achieves deep penetration. This process is repeated on the reverse side strengthening the welded joint.

After completion of the structural repairs, the bumper is sanded and a flexible filler is applied to level the surface.

The bumper is sanded in successively finer grits until a smooth scratch free surface is achieved. A primer coat is applied and the technician performs a detailed inspection and repairs any surface imperfections.

After sanding, the bumper receives a final application of black coating which serves as a prime coat for color coated bumpers or as a finished coat for black bumpers.
