I am wanting to know what material is used for the tubes attached to the Predator mask in various models. Also the tubing for attaching the shoulder armour to the chest armour. As seen in this wolf model.
Stoods, I own the model in the picture, I'm not exactly sure what the tubing is made of but I would suggest black twisty ties like the ones you find in action figure packages. You can leave the little metal wire inside the sleeve or remove it. If you keep the metal wire you can bend it whichever way you like before gluing it together. I'd personally remove the wire then glue it.
If you like you can message member DisturbedEarth and Bobby can help you out with the detail, he's the one that built and painted that kid for me.
