Does Etex have a shelf life? Should it be used up in a certain amount of time?
Thank you for any info

For epoxies in general, I don't think the resin component of epoxy ever goes bad but it can crystallize if it stays cold too long. If it does, you can heat it to make it liquid again, no problem. Hardeners are different and there are various types depending on the epoxy. Most of them won't "go bad" in the sense of not being able to harden the resin, but they will yellow or turn brown with age and if they do, that will carry over to the mixed epoxy. I've used hardener in epoxy that was years old and brown with no apparent problem - as a glue, not a finish. I can't judge whether its strength may have been compromised to any degree. Maybe yes, maybe no. All you can do is try it and see.

I bought some Etex about 1 1/2 years ago and still use it for certain things. It still looks and acts just like it did the first time I tried it.
