Anyone know exactly how conductive this stuff is? Resistivity value?

It's volume resistivity is .0004 ohm-m when cured properly according to the manufacturer.

Can you solder to this epoxy when fully cured?

You should solder first, and then coat with conductive epoxy and cure. The epoxy typically improves the electric contact accomplished by soldering. Good luck!

will a fresh mix of this epoxy bond to the cured epoxy?

I do not know. After a careful reading of the warnings and dangers of this product I put it on the shelf unused. I learned how to solder. Just saying.

Does this stuff ever harden or is it always soft?

The stuff hardens in about 1 hour. It is dispensed from a hypodermic type dispenser and can be mixed with a kitchen knife or small spatula. Have some alcohol readily available to clean up your mixing and apply tool and possibly you. I found that it conducted current quite well. When you are mixing and using this product it reminds me of using bondo.
