Well the arms didn't stay on very well with plastic cement, I don't have a welding type glue, pins and Ca glue worked fine, there is enough plastic for pinning and isn't soo hard to do, It worked very fine for the head, you can have a posable head this way and is easier to paint.
I don't want the arms to fall apart when I will paint and decal or to ruin the paint gluing the arms after.
