I am developing slides by myself, with Jobo ATL 1000 and E6 3 bath kit. This article is really interesting, and I will try to make this chemistry by myself!

I have one question, if anyone can help. I found 3 boxes Agfa E6 (I think 44 process it is!), 6 bath. Boxes and bottles are still originaly closed and were stored in dark cold environment. They might be older than 5 years. Is there any chance to use these things without any major problems?
