Just a suggestion on an alternative solvent, when I tried this on RTV, methyl ethyl ketone (MEK) was much better than acetone.
Acetone had the same effect of turning the RTV to gum, whereas the MEK resulted in a nicely runny mixture. It evaporates and produces the desired end result in RTV. It might be worthwhile trying this with epoxy.

Side note for folks outside the US. MEK is available in Canada only, it seems, in lacquer thinner. Apparently it can be used to make crystal meth or some such, so it's not readily available.

I've had good luck with putting the resin in the microwave for a few seconds, then mixing it.  It will set up a little more quickly but its water thin if you do this.  For large layups I do this every time since I go thru the epoxy quickly, and it makes the fabric wet out much better.
