Anyone have any experience with, or opinions on how long 2-part epoxy stays good, after you open the tubes? I used about 1/3rd of a pr. of epoxy tubes to splice some siyahs, back in March, earlier this year. Their lids have been sealed-up tight since then (about 8 months). Getting ready to do a handle splice. The product is Devcon 2 Ton Epoxy. The 30 min handling / 30 min set / 8-12 hr. cure type.
