I am in the process of reassembling a set of kitchen chairs. Many of the joints are quite loose. I am thinking epoxy would give me more working time while doing the glue up as well as take up some of the "gaps" at the joints. I don't think that yellow wood glue would give me time to line everything up and get them clamped up. I have never used epoxy in this type of application. My concern is the outlay of cash for the large containers. I cannot speculate the next time I will need to use the balance of epoxy I will have to buy. I know I can buy the smaller quantity in the two part syringe type package but think I will need several of these for the chairs. I am concerned by the time I would use up the remainder of the larger containers them may be no good. Any idea on the shelf life once opened? Any suggestions or direction would be great. Thanks in advance. Chris
