Forgive me if I am missing the point but isn't the pad on the bottom of
the IC there for the purpose of being soldered to a matching pad on the
board? Isn't it necessary for heat sinking or grounding?

Here's a page for an overcoat touchup pen sold by DigiKey:

and here's a page for high temperature Kapton tape that can be used
as a temporary solder resist covering:

oops. let me try this again...
Hello all,
I have an 8-pin SOIC that has an exposed ground pad on the bottom of
it (Analog Devices AD8000), and find that there are a couple of vias
under the IC that I am afraid might be shorted by this pad.
Does someone know of where to buy a small quantity of touch-up
solder mask so I can cover the IC pad or the vias before wave soldering?
Thanks much, & Merry Christmas.
