Hey Terry...

"glueing" is probably the wrong term to use for polycarbonate ( Plexiglas)
most bonding methods used for plexiglas involve a solvent that 
melts/joins the two peices together  ( like the old style model cement
used for making cars and planes etc)

As far as Lexan, there is an item that works relativitly well with 
it...  its called "Lexel" comes in a tube like latex caulking and is 
used in the application gun as such...
takes a while to dry but when it does its stuck   ( btw it has the 
solvent in it similar to that of the plexiglas solvent   kind of 
reminds me of the old airplane glue ;) )

there is a good chance that this stuff will bond 
plexiglas    ohh  and btw  its clear too....
