We use a product called "PACOVIA" from the Paper Corporation of America, I
believe.  This is a plastic sheet which seals the top of the panel when resin
is flowing from the bottom side.  It works well but does leave some residue on
the epoxy surface.  Contact me directly if you wish to discuss it more.

Greetings All,
    I'm looking for a more effective and cost efficient method of
blocking resin squeeze up hole barrels on sequentially laminated
multilayer PCB's.  Any and all suggestions are greatly appreciated.
