Rod, I think the rubber would be good for small items, but would be
very expensive for this.
The usual way of creating a mould uses just a relatively thin layer of

on the outside. So cost, which I have not worked out at all, might not
be quite as bad as you initially think.

Although common it frequently goes undiagnosed.
