Polyurethane? ? Answered

Great class.
I want to reproduce my own custom made tiers for my plastic model cars. I understand the molding process, I want to know what casting media to use for the tires. I want them to be flexible like the vinyl ones from original kit. So what would should I use?

You can use silicone rubber mold that can be tinted black . There are different types of them from very soft to hard ones. What you must be very careful, is to use the proper release agent to avoid your cast material adhere to your mold, unless is metal.
