Duct Tape

Eastwood company...for the plastic welder...I believe there are no adheasives that work with thermoplastic......but I could be wrong.

Clam juice.

Try a productr called "Goop" in the sutomotive section. This stuff will stick almost anything together. It is made for adhering the trim (usually synthetic or bubber) to metal. I did it in the cold of winter and that was two years ago and it hasn't so much as lifted a corner.
http://www.naturalhandyman.com/iip/infxtra/infgoo.shtm is a link about Goop.

The only "Goop" I've ever seen in an automotive section is hand cleaner.

Hee hee hee. Yeah, maybe a nice clam pate, slime that on there and bake it in a body shop oven, 350 degrees for 1 hour, turning once. Lightly pepper and serve with crackers and whine, err wine.
