Sometimes, not always but sometimes the epoxy will stay tacky if you use 70% alcohol, that is 30% water. Most of us use 91%. Same alcohol, just less water. Usually the 70% works just fine but it's that one time it doesn't that will make you start stocking 90% in your shop.
Try it, if it is tacky clean it up with acetone and do it over, not the end of the world.
Okay, I see. How much alcohol should I mix in?
About this much. TLAR. How thin do you want it. Jester just brought up heat, just mix some 30 min. epoxy up and heat it with your covering gun until it is runny enough to use.
