Preparation of pp/epdm and your thoughts on it

I've identified my bumper as poly propelyne epdm or >PP EPDM<

The structure that is melted to it is >PP COPO< which won't be painted but will be over sprayed.

Will I need adhesion promotors for this?
What filler can I use with this?
And any special thoughts on preparing this for epoxy and high build?

The structure is separated in 2 spots from where the tabs connect the structure to the bumper. I would like to repair it. How do I do this.....can I melt it back together or use sem plastic repair.....

I did glue it with the sem but in flexing it too much it came back apart. Granted it may not have done this on the car but I would rather have a better solution.

On another note. In the front lip there are hairline spider cracks. Any solutions?
I know they will come back if I don't take care of it.
 
polypro definitely needs adpro. it will plastic weld easily so you can mely broken tabs back together. it will work much better than adhesive. same for spider cracks.
