I need to create a mold from a piece of plastic that is roughly 24"x8". Answered

     I want to make a mold of a piece of colored plastic, the problem is the plastic is thin walled and fragile. I was wondering what the best mold material would be for it. I need to preserve the original so a gentle process would be the best. Any help would be appreciated and thanks in advance.


For what purpose? (I matters)


Liquid silicone or one of the other pourable molds. Put it in a tray and cover it with liquid silicone. like this.

Or look over on the right side under "RELATED".

Or search this site for "silicone"
