Did that my friend. Even tried a heat gun in a spot or two. I ended up adding nearly the entire 2 oz of MEK to 8 oz of resin to make it kick. I couldn't stand it. The area that was starting to set had squishy resin all underneath so I ripped it all off. Wiped down with Acetone and I am ready to go again. I hope that I don't wear out my welcome at the glass shop tomorrow morning.. I am stupid for not trying it first. I just got back from the getting place with more supplys if my heart was just in it..MEK three tubes from two sources says at least one of these are still good. Waiting on that magic temperature here now. No good glasswork can be accomplished without the 110 degree heat index.
