Silicone painting medium substitute for PSI-641?
I am going to be making some silicone puppets, and I watched the awesome tutorial about painting realistic flesh tones on silicone. I have looked online for the PSI-641 caulking that is recommended in the tutorial, but all the companies I have contacted have told me that it is discontinued. What other silicone can I use as a medium? Can I just use a little bit of the same catalysed silicone that I am pouring up the mold with?
