I need at least 10-15 PSI pulling power without
the "stuff" letting go from the surface. In other words, plenty of
stick...



It depends on the epoxy - some works great and others don't. 15 psi is
nothing if the correct type of epoxy is used. Could be a PITA to clean up
since epoxy sticks so well - the good thing about it is it dries clear or
slightly yellow.
