I'll look for some of that foam. I was concerned about the glue
because sometimes it can actually eat away at the styrofoam and not perform
as glue but solvent. Don't have a Lowe's around here yet but one is being
built as we speak. I'm sure I can squirrel something up though. Thanks for
the answers and ideas.

If I can think back long enough (and it is a real challenge), there was
no Lowes where I live so it might have been Home Depot where i bought
the tank insulation.
