I've gone through this as well...
Thought you all would like to know that the front chin spoilers on the 928 ISN'T made from palstic. Believe it or not, it's rubber! That's why everyone has such a hard time "plastic welding" it.
My solution was four fold...
1. I made small sheet metal brackets to bolt on the bottom
2. I got some small steel welding rods and cut them up as a re-enforcement to step 3...
3. I ruffed up the back for the spoiler with anything at hand (quite rough, used knife, files and wood chissels) and then applied the plastic repair epoxy (hardends to a maluable yellowish substance) over the rough area.
4. Once the plastic epoxy was pretty much setup I too some fiberglass mat and some more epoxy to glue the mat into the whole mess.
It might be over kill, but it's never come part on me. Even after bumping those curbs a few times since.
