Any Room Temperature Vulcanizing (RTV) Silicone rubber will work for this.
Look at the tubes of bathtub sealer at your local hardware store. GE
and 3M make very good products for this. Dow-Corning is another. Make
sure the stuff you buy remains flexible after it cures.
There is also a product that is used by the the electronics industry
that is excellent for this use. It is called Flexible Solder Mask. If
you have friends that work in electronics, they should be able to get
some for you. We use it at my company and the Government Inspectors
have declared it to have a shelf life of 6 months, then we have to
throw it away. I've got some that is still useable after 4 years. I've
used it to make many molds for my model cars and planes.
