I repaired the cracked flexible urethane plastic front bumper on my 3rd Gen Camaro using a GM recommended adhesive (3M 08101). I have found that this material is no longer available. I went to 3M to get their advice on a substitute material for this purpose. The 3M representative recommended material is 3M 05887 EZ Sand Flexible Parts Repair, that is a 2 part Epoxy intended for flexible bumpers. He said that it is good for urethane bumpers and that the optional adhesion promoter should NOT be used. I have links to the 3M repair information below.

My Camaro and other General Motors bumpers use this urethane bumper material. In the 1970's, 1980's, and 1990's, General Motors often used a urethane plastic material on various Chevrolet, Buick, Oldsmobile, Pontiac, and Cadillac models for front and rear bumpers, and certain other flexible body parts.
It appears that my Camaro front bumper was hit at one time and had about a 2 inch crack near the right headlight. The repair process for flexible urethane bumpers is special because urethane is a thermoset plastic and adhesion of repair materials can be difficult. General Motors service information specified a particular material and process. This repair required a 3M Structural Adhesive kit # 08101 for crack repair and reinforcement. The 3M 08101 material is a flexible adhesive that will adhere to the urethane if the instructions are followed. I used this to successfully repair my Camaro bumper cover. Now, the 3M 05887 is recommended as a replacement adhesive and filler.

If you choose to do this type of work, be sure to use the recommended protective equipment for the chemicals you use.
