Went and looked at my work from yesterday mostly inspecting my progress. What I found I can’t believe, never seen this before, but the thirty minute epoxy has not cure, still tacky left my finger print on the surface. I mixed it right and it’s worked or hardened when I mated the wings. It’s been Rainey the last two days kinda humid, but cool and not warm. Strange. Why it’s not cured. It’s two years maybe three years ago, when I bought this two part thirty minute epoxy. I’ve used my smooth and easy it’s at least twenty years old. And it works sands easy made by hobby proxy. Used it to seal my engine mount and fuel tank area. I’ve got two packs of it one I haven’t opened. But I keep it in the fridge. Along with my dope and spray paint. I am always concerned about it freezing,but my temps in the Hanger where I live is always nice. Guess I will let it set and see what happens. AJ
