MARK JOSEPHSON ASKS:

>>I just bought hundreds of RBT mounts for that purpose, and I suspect I will
stick with those.  RBT's knock aluminum right out of the water.  Say, Jon,
something that just popped in my head...What kind of plastic are the RBTs? 

Mark, Franz at RBT has sent me info saying that the mounts are made of
Polystyrol P457K  Short Name: PS.  As far as being archival, Franz says that
there should be no long term effect using these mounts, and that this
compostion was chosen for protective and structural purposes.  JON GOLDEN RBT
