The lesser of two evils

 With the air bubble problems I'm having with easycast, I thought using a slow setting resin shouldn't have those problems. Apparently not. After waiting for an hour to demould, not only did it have large air bubbles, it had hundreds of tiny bubbles scattered throughout the surface.

  

  So I guess I'll stay with easycast until I find something better. For now I was able to reduce the large bubble gaps by making larger air vents.
