How do i make moulds for Resin? I have parts that need to be cloned, and am needing advice on how to do it. Any ideas?

use a 2 part RTV. it really depends on the complexity. on a simple part you could use a 2 part Putty or Silicoane selant. I prefer Smooth On's Mold Max 20 it's a 10:1 2 part RTV rubber that cures fully in 24 hours. It also has a very good tear resistance for deep Undercuts.
