Trying to use glasscast10 to fill a plastic honeycomb structure.
Mixing 2 to 1 ratio 100ml resin 50ml hardener with few drips of yellow pigment. After pouring over the plastic honeycomb and heating the resin it is nice and clear without any visible bubbles but during hardening over time i get small trailing bubbles building up. What am i doing wrong? do i need a pressure pot or do you think there is a reaction with the plastic honeycomb.
