Hi, I am a big fan of Aquilim 315, and have successfully been using it for a few years now. I bought my last 16 oz jug in Feb 2020, and have it in my basement, which is semi climate controlled. (Have a dehumidifier running and normal house temps) Having had a lull in contract projects with the pandemic, I had not used it for much of the last year. Fast forward to the last few weeks, I notice that my glue is not bonding very well at all. I am gluing flesh sides together, I am letting it dry to tacky, then hammering it in place, then machine sewing. This method has worked for me in the past, but it is not bonding right now, peeling up in most places. It still looks and smells the same to me. I tried shaking it up, curing it with the heat gun, thinning it slightly with water., still not working. Can it go bad? I am just going to order a new bottle, but wondering if anyone else had this problem. I ordered the last jug in February and maybe it froze during shipment, but I don't remember it having a problem then. Thanks!
