According to my 8er brothers who have faced the same plastic fix as me and our FTP screw tabs (worst structural design I've ever seen BMW make), these two products are apparently great at fixing a plethora of plastic breaks and or MAKING plastic parts for chunks of plastic missing from something.
Just figured I'd share these products here.
I have the Q-Bond at home and plan on fixing a totally separated plastic tab from my light bar (FTP) assembly. I can let you know about the results, but from what I've read and the videos I've seen of the Q-Bond in action, the chemical reaction is MUCH more likely to keep plastic parts together than simple Crazy/Gorilla Glues. as with everything, prep work is the basis for a great repair, so I'll sand and v-grove the edges then bond plastic parts together and build up levels.

has a lot of products for different types of plastics or materials. BUT here is the one I was referring to specifically.

they have neat videos on their website on how to use it. seems simple and perhaps a better product than Q-Bond ,but Q-Bond was only $20 CAD for me and available easily, so I'll try that first.
