Do any of you know the type of plastic used in the leather bags for a Road King Classic? I've got some welding to do, and I'm not sure of which plastic rods to use.

Seems the previous owner let mice live in the one bag, and they gnawed a corner out. I'm planning on welding it up with a soldering iron. But, I need to get the plastic right.

Did successfully weld up some cracks with the soldering iron. Was pretty pleased with myself for it.
