A general warning if I may...
DO NOT pour resin in any large amounts. The heat produced by the exothermic reaction increases parabolically and it could very easilly catch fire. Also the fumes emitted by a boiling then burning resin mass are toxic.
Softly softly poury resin monkey, layer at a time. I've seen what too much too quickly can do and it was quite frightening!
