So I had an incident and ended snapping off a small section of the lower front skirt on the passenger side of my XFR. Contacted the dealership as it appears the lower section could be easily replaced however they say it is not a piece that can be ordered, you have to order the complete front bumper cover assembly.
It is a clean break and the piece fits back nicely but I'm wondering what the best type of glue is for whatever type of material this is. Any suggestions as it's going to be a onetime shot trying to fit back into place.

 

My guess would be epoxy specific for plastics, but it's only a guess.

 

Post up a few pictures.

Your best results will be if you can "back" the break with a small piece of aluminum or other material with whatever you glue it with. If it is possible to reach behind and it won't be seen after the fix. Make sure you give the backing of the plastic a good "key" to give the epoxy more surface area to grab onto.

Most likely you will be able to use a JBWeld product. They make several types of 2-part epoxys.

 

Another thing you can try is to get online and search the recycling yards for that part in your body color. I would bet you could get that whole piece in your color for a fraction of the new part (even factoring in the shipping yo your door).
