Hi John, Let Me try it. Let me try it. I've been a member of composite airplane forums for years and have hundreds of dollar$ of Aeropoxy in a storage unit. At least one contributing member of those forums has substantial work in the epoxy manufacturing and evaluating field. If low temps are the only issue, it is not ruined. It's just waiting for appropriate temps to finish curing. It doesn't spoil. Low temperature will slow and/or stop the curing process until the temp warms up to around 100 + something degrees. Once the temps hit those temperatures it'll finish curing and developing it's max strength. (To exotherm is not normally a good thing. You get this from an excessive quantity of mixed goo and the stuff can actually get hot enough to self-ignite.) Always a possibility is to wonder if you mixed the ratio backwards. Rather than x-amount of resin and y-amount of hardner, you did y-amount of resin and x-amount of hardner. While Rutan taught composite guys to mix for at least 3 minutes, scraping the sides and bottoms of the cup and all, I'm aware of many guys who mixed for much less than Rutan recommendations and flew their airplanes for years. I'd say, get your temps up and see what develops.

I put a layer of glass on my starboard elevator 2 days ago. That night we had a power failure and the temp dropped to around 64 degrees F, now 2 days later the resin is still tacky in places. Have I just ruined the lay up? I used Aeropoxy PR2032 with PH3660 hardener.
