Hi, i have been buy your products for a few years now. I use the EL2 LAMINATING Epoxy with AT30 SLOW hardener. I have a bottle which is around 10 months old, its unopened but i cant find a date on the bottle. Could you please tell me weather its still good to use ? / How long it should last for ? Many thanks Rupert

I still had a small amount of West systems 105 leftover from my very first purchase in 2005 ... I did a test with new hardener, and it worked perfectly after more than 7 years!!
My conclusion is, that the Resin will last for years, if kept cool, dry and dark. The hardeners however will not last much more than a couple of years, even when ideally stored.
