No - not a good idea.

No, but you should be able to buy epiglass hardener separately (if they package it in a small enough quantity) - its been awhile since I bought any Epiglass products

You want to mix different brands? That is not a risk worth taking. There is too great a risk of chemical incompatibilities.

Nope not a good idea. I've never tried it, (who would?), but I'm pretty sure you'd be wasting both resin and hardener if you did.

I wouldn't try mixing them UNLESS the vendors could both tell you what the hardener really was (the actual chemical) and the two were actually the same chemical, in the same concentration or one close enough to work.

I'm always inclined to experiment. I'd do up a small batch and stand back!

Ya never know what'll happen!

The epoxy resin is normally all the same stuff. It is the hardener that is different and unique to the manufacturer. I would try a small amount as a trial, at the hardener mix ratio of 5:1 and see what happens. DO NOT mix different hardeners.
Oh and hardeners for epoxy paints don't work in Resin nor the other way around.
