Then its just apply your release of choice as you would a "normal" mould

I am wanting to use HIPS so that I can dissolve it in limonene after the part has cured. Will the marbocote come away when the HIPS dissolves ? What do you use to polish the final coat with and what is your preferred release agent for this type of mould ? Edited 9 Years Ago by make_pr
