Easy to work with
I used my mold with epoxy resin purchased with this company. Very easy to unmould and shinny pieces. I tried it with Vaseline has a mold release but that particular piece came out cloudy. No need for mould release. The only down side is that you can see the fine marks of the plastic in the finish piece. You can only see them in direct sunlight and looking closely but they are there. I will try to do a thin top coat of resin to see if they disappear.
