I am in search of a white rtv mold compound that I have seen from
only one manufacturer. International Manufacturing from Philadelphia
used it years ago, but I can no longer find that compound. It had a
nice feel (pretty soft actually), but it did not tear very easily.
We have been experimenting with dozens of mold compounds and I have
yet to find the “perfect” one. If anyone knows where we can find the
white compound, or has any suggestions about their favorite
compounds, please pass it along. At this point I am only interested
in the RTV type.
