What's the best glue for plastic car body parts?

Joe Meehan’s right about super glue not being what it used to be, but if you can get the type of super glue that has a seperate bottle of “accelerator”, it works pretty good. You see, super glue is a type of anaerobic sealer- it only will harden in the absense of oxygen; and it also needs to be pressurized; these 2 things happen when you push the 2 broken pieces together. Problem occurs if the

break has jagged edges and you can’t push it back together just like it was before it was broken- the resulting gaps don’t pressurize the glue, and the unpressurized glue doesn’t harden. Epoxy type glues, not being in the anaerobic sealer catagory, don’t have this problem. Anyway, back to the accelerator- if you spray the accelerator onto the break right after you push the 2 pieces

together; (of course you’ve already applied the super glue to the broken edges); the accelerator will cause even the unpressurized glue to instantly harden, though you may need friend’s “third hand” to spray it on to the work. I’ve used this stuff on broken parts that I swore were beyond hope and it has worked admirably.
