Pretty much it. There was a hole where the end of the neck opened to the outside of the mold. A large quantity of it exited that hole too. Waited till it set up and then pried the mold apart. I used Vaseline as a mold release but an error was in using the home spray can stuff. It doesn't seem to age well and it is not very sturdy. If you are going to do a good job, use the right foam.
