I am using a 2 part slow curing epoxy for my Arigs. It takes at least 12 hours to cure when poured and kept in the house, unlike my previous casting resin which set up in a little over an hour.
It is also very cold out where I have to paint them so I decided to try making some colored ones that I wouldn't have to paint. I put less than 1 drop of plastisol colorant into my mixed up epoxy, stirred it up real well and poured it into the mold. That was 36 hours ago. I took it out of the mold yesterday afternoon and it was not hard. I have checked it this morning and can still make thumb nail marks in the surface.
Before I do any more I thought I'd ask if this is a no no.
