I have been using Modostuc for more than 20 years. Though I don't
use mostly Modostuc anymore, I still have it in the studio and I
know many people who also use it. I have seen mould growing after
time or when many different people in one studio use the Modostuc
because some will be less careful than others. In general, if you
keep a piece of mylar cut to the size of the tub covering the
Modostuc and in contact with it, plus the original lid, it should
last a long time. When using it, remove the amount you need, close
the tub and never put leftovers back in the tub. I always remove a
larger amount from the tub and keep it in a small container for
daily use.

Modostuc is also available in smaller tubes. You can try that. I
would still remove a smaller amount and keep it in a tightly closed
container for daily use.
