Duane,

We ran into the same problem about two years ago.  We were having to
clean the boards with acetone to get the residue off, not to mention the
time for actually masking and unmasking the boards.  We now use Spot
Mask, a liquid latex rubber compound from Weller.  It goes on pretty
fast.  We air dry the boards, although sometimes when we are in a pinch,
we use the oven from an old Amistar P&P machine at 347 degF and 3.5F/M.
Unmasking is a breaze.  Just peel.

Hope this helps.
