About a year ago, I was given a box of 6-minute epoxy.

About a month ago, I gave it away - unopened

I just don't see the point in 5 minute epoxy. It sets in 5 minutes, but it takes 24 hrs to cure - same as 30 minute epoxy, but you get far less working time, and it doesn't bond as well.

To me it's a no brainer. So what if I have to wait an extra 10 or 15 minutes? It's not like I build the entire plane with it. For the few things I need it for (Usually only joining the wings and adding the tail feathers) I don't mind letting things sit overnight.
