As for the idea that everyone ought to be thinning epoxy only with denatured alcohol.... chuckle chuckle.....

Yeah right.... or actually..... no, not even denatured or denuded or detuned or any kind.

Truth is, you can thin it with water. The proof is given by the guys using drug store water, the 30% pure stuff that has 70% isopropyl in it. chuckle.... ok ok......

There is another group of epoxy thinners that uses something else. I think it's acetone. And it works too.
