I am currently attempting to cast a Dragon Skin (platinum cure silicone rubber) suit to fit over a one-sixth scale action figure. The mold that I am using to attempt to make the suit is made of urethane resin. I have made 4 castings so far and have had no luck with any of them. I am experiencing issues with several voids and thin spots throughout the casting. I am using a pressure pot but that does not seem to help at all. Is there any advice that anyone might have as to what I may be doing wrong? I'm new here so I do apologize if this question is in the wrong forum. Thanks all!
