I might have been tempted to toss that stuff away regardless, due to the reduced hazards of Jeffco. The original question was where out-of-date epoxy and hardener could be safely used. I would opt for micro only. After all, every epoxy joint is holding **something** together, and I don't want any of those joints to fail. If the armrest pops off I'm probably going to survive, but I guarantee you that my passenger would never fly in that airplane again! ("That's the same stuff holding your WINGS together!!!") I already get enough grief about "those two little bolts holding the wings on" from people who don't understand that these are the biggest aircraft bolts I've ever seen in a light aircraft. It would be hard to explain away a bunch of cracked epoxy joints with "Oh, that's only secondary structure. Don't worry about it." I find that I use up an entire gallon of epoxy in a slow building year, and more when I'm really cranking. So I'm rarely tossing out expired epoxy, although it has happened on occasion. Discarding out-of-date stuff is therefore not a significant expense for me. I write the date I received it on the bottle with a Sharpie marker so I don't forget. I guess I need to close my tail this summer. My hysol will be expiring in October. Now THAT stuff is expensive to replace! - Rob Wolf >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://members.olsusa.com/mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please remember that purchases from the Builders' Bookstore assist with the management of the LML.
