        The "green stuff" is called solder mask... and it won't hurt anything
if it flakes off, at least not directly. It's just there to keep solder
from flowing all over the circuit traces and wicking its way into places it
shouldn't go when the board goes through the wave-soldering machine, and
has the side benefit of sealing and protecting the traces from oxidization
and contaminants afterwards.

        I don't think there's much you can do to stop the flaking, short of
coating the entire board in epoxy. :)
