I've used an Epoxy resin in the past called Composite Materials Inc (CMI)
The label says made in Vancouver B.C. I've been happy with it . Last week I bought more from the local suppler and the brand has changed. It is called Jeffco, from San Diego Cal. The supplier says its the same stuff .

The hardner seems a little lighter in color but other wise it seems the same.

Does anyone know about Jeffco, I'm just curious.
