Automotive Plastics: Identifying type of plastic, honda crx, rocker panel

Question
I would like to identify the type of plastic used on the door caps and rocker panel covers on an 1985 Honda CRX. Mine are cracked and I would like to repair them with epoxy of some sort.

Answer
Dear Jeff, in order to identify those plastics you must detach  them from the body. In the back side look for a code similar to this: >PP< which stands for Polypropylene or >PUR< = Polyurethane. These are just examples. Let me know your codes and I will recommend the best welding procedure. Normally we do not use adhesives but rather the same Polymer for successful repairs. Thanks for asking.
