Bluetac and Funtak (spellings of both?) are also brands... One's
made by Elmers, and one's made by Dap (forget which is which).
My local Lowes keeps it with the epoxies and CA adhesives; the
supermarket keeps it in the office and school supplies aisle; Wal-mart
should have it in both sections, though I think they keep it with the
epoxies and paint thinners at the store I frequent.
