We use fairly soft RTV rubber moulds, probably a bit softer than the
ones Jon
uses at GZG (but easier to produce). After more than three years of use,
the
first ones are starting to wear out, so I guess we've had several
thousand plus
castings from each one before they've given up the ghost. The biggest
problem is,
as stated above, that too much undercut detail can cause the mould to be
torn if
you're not gentle enough when taking the castings out. The main reason
we've had
to replace moulds is damage caused by careless handling rather than
wear.
