Understand, no one makes the epoxy, they only package it. That likely includes even Devon. They buy it in 55 gal (45 imperial) drums from the manufacturer.
You can pick which formulation you want, pot life, mix ratio, strength. You can then add stuff, like Carb-o-sil , a thickener and firmer, mini fibers, another thickener and strenghtener, or fiberglass, another thickener and a even greater strengthener.
I use earth pigments to get the brown. Burnt Umber. The local plastic dealer has a rack of dyes for fiberglass, I imagine they would work for epoxy.
If no one makes the epoxy it just magically appears?
Laughing!
There are multiple manufacturers. IIRC you advised G-2 which was a spectacular formulation by Industrial Formulators there in Canada, eh. It was such a good company West bought them a number of years ago and now makes their best formulas under their "System." Plain old carbon black strengthens epoxy a tremendous amount and better black does an even better job.
