Thanks Hipnotic1425,
I used:
Rebound25 silicone rubber ( I used the double mixing method = 1part A to 1 part B mix in a mixing cup, then mix into a second mixing cup. This method helps make sure the two parts are fully mixed.
Smooth-Cast 320 for the castings (320 is harder than the 300 & it allows you to tint the resin.)
Black Urethane casting tint for the smooth cast (allows you to see the layers)
Ease release for the Mold (Once you have the mold completed, you should coat it with ease release
I hope this has helped.
