OK, so the last time I moulded and cast ANYTHING was about 2 years ago. I got some pinkysil and 4PU from Barnes when I was down in Sydney (yes, I could have had it shipped to me, but I was around the corner at RPA anyway so 2 birds, one stone.)
I've got some terrain pieces that I've made up that I want to cast. I go to their site, and 4PU seems to be no more. I know about the changes they had made to 4pu - and I figured I'd adapt - I've got scales, I've got good "instincts" and I know how to do calculations.
Is it still around? If it isn't, what is the current replacement (similar properties, including pot life).
