Hey all, I don't know where to post this. Maybe a Mod will make a better choice, but.. there is a product that 'welds' plastic and fiberglass cracks and even broken pieces.
It's called Plastex.

It works!
Don't throw away that part because it's broken!
I used it on Fiberglas parts on my Ducati and now on the plastic side skirts on my recent GTS.
Just wanted to share that.
