Hey so I just put up a post about looking for a person to make a custom Grimlock which I still am but I also would love to make one of my own. So I was seeing if anybody here on the forum could help me find out what materials I would need to turn a Hasbro Leader Class Grimlock into a screen accurate transforming figure I would like it to look as accurate as one I've seen on here that look like this one, thanks to anyone that helps thank you!
