I did a tutorial on it on another model car forum years ago. But, I would say it's gone by now. Someone mentioned then about having it cast. But, there wasn't much interest in it. So, I didn't bother.
I can't access my Photobucket account to even see if the photos are there now. It would be impossible to explain the process without them.
I don't know if I have another kit to do a comparison/another tutorial on. If there's enough interest, I may see what I can come up with IF I have another kit.
