Dale,

I picked the brains of my resident expert in the machine shop who said there
are many different kinds of silicone rubber, some oil based, some water
based, some resistant to high heat and some resistant to strong chemicals
and most all of them suffer from the same problem: they dry out. And then
they shrink. And when they shrink they crack.

But, there is hope if one can find a specialty type of silicone that has the
property that it does not shrink.
Who has a non-shrinking silicone rubber and where can you get it? - JZ
