Thanks all, I think I figured out what the problem is. This is the deluxe version of this kit. The normal version was molded in a grey plastic, without the shiny brass color. I am beginning to think that the brass color is some form of paint. I can scrap it off and the plastic is grey underneath.
So it probably is some sort of coating which is preventing the glue from curing correctly. Both for this kit and for Godzilla, when the joints broke, you could see a residue on the plastic from the Pro weld. Which makes me wonder a bit.
The tail has been pined and it holding up really well. It feels very solid now. (Well it is one solid piece, so it should feel that way.....)
Progress has been made today. I figured out how to use a texture stamp with Aves, so thing should speed up now!
The main body has its seams done, the legs are done with the feet attached. If my experiment with the texture stamp works, I will be taking care of the tails and necks tomorrow!
Norm: Where did you buy that resin kit from? I tried to back track it from the link you provided, but I couldn't find the original site.
