Just wanted to let everyone know that 3M Super
Strength Adhevise is
 absolutely THE WORST adhesive to use on plastics.  I bought it
 specifically for gluing borken plastic pieces as it is advertised as being
 for such, but all it has done in the two projects I've used it with is
 make a big mess and ruin everything.
 All it does is melts the plastic, causing the broken edges to no longer
 fit snugly, and then it gets all over your fingers when you're trying to
 press the parts together, which they don't do.  It either doesn't make a
 good bond and requires regluing which then builds up glue along the edge
 ruining the fit, or adheres but the end result looks shitty. 
Thanks for the heads-up.  What we should do is post what we've
found that works for the plastic parts and other bits we're
likely to run into with classic systems.
I myself haven't found anything good for plastic.
