Wonderfull stuff!  It's "methacrYlate" btw.  This is a two-part
very-fast-setting acrylic with amazing "bite" into most plastics.  I
try to always keep some around.  Seems almost miraculous sometimes,
although I think even it will be defeated on polyethylene and those
wonderful waxy-slick-feeling industrial resins used for intricate
parts like turn-signal actuators and such.  Not sure about nylon.

Another uniquely useful adhesive is Elmer's StixAll (sp?), a tiny
little tube of RTV silicone for about $6.  Releases acetic acid
during cure, so that limits it a bit.  But unlike gasket maker
silicones, this stuff is formulated to be stickeeeee, and will stick
to an amazing number of materials.  Cures bluish-clear translucent,
rubbery.  Overnight cure.

Since I'm talking about superlatives here -- 3M 5200 caulk/bedding
compound.  I believe it's a polysulfide rubber.  Takes two weeks to
cure, but it's so tenacious that they make another version whose only
attribute is that it isn't as strong as 5200.  5125, maybe?  Like
everything else from 3M, it ain't cheap.
