John,
You are doing WHAT?
Mate,
An entegral part of the epoxy curing process is the chemical reaction between the resin and the hardener. You are introducing another chemical into that process. That chemical - metho, has the capacity to disolve uncured epoxy. or at least compromise its strength and integrety.
I am no industrial chemist but compare this to painting a wall of your house with enamel, then wiping the wet paint down with a rag soaked in thinners.
Now, go outside and give your self three sharp upper-cuts and repeat to your self 100 times, "I won't mix metho and epoxy- I won't mix metho and epoxy"
Seriously mate. I wouldn't dream of doing something like that. There are others here who have more exerience than me and they might be able to share some light on the subjuct. I run by the motto with things like this " IF IN DOUBT - DON'T"
