This blog post has been making the rounds:
So it is a good thing that I have sworn off finecast. Not only do I like metal models (I am trying to stock pile them before they are not longer available), but if that melting it true, I can't buy any.
There have been many times I have left my army in my car during the day and everything has been fine. Now when I say that I have left it in the car, I mean in Phoenix the temp gets up to 115 degrees and I do not know how hot inside the car gets, but I have never had a problem with metal and plastic. If I do that with finecast I will be coming back to a puddle.
