You mate them with tons of rivits or self tapping sheet metal screws and metal strapping on the back side. Then there is a product called Duramix 4040 that you can use to combine the two bumper sections together. Duramix also makes a pin hole filler that you glaze over it all once the 4040 has been sanded down to fill any minor stuff. Then you do the basic prep on for urethane bumpers and prime it and paint it.
That's a basic run through, as there is a lot of cutting sections out of the bumper you're trying to mold into the Contour bumper and other fitting aspects that need a lot of attention.
Drerok molded a Cobra-R lower section to his front bumper and that's who Exdelayed got a lot of his info from IIRC.
