Rubber molds

There are numerous places online, where you can get the rubber compounds for mold making. The first thing you need to take into account is whether or not the compound is self lubricating. Self lubricating, means no mold releasing agents are needed.

While that might seem like a good idea, I stay strictly away from the compounds that are self lubricating for one good reason. If you ever need to repair a mold, you can't with self lubricating, because the new batch won't bond with the old. Since I always want that avenue open to me, I make sure it is not self lubricating and does require mold release.

I'll be back to finish later.
