Hardman Double BubbleYellow-Label Machinable Epoxy 100 Packs (#04002)

I worked for a film manufacturer for years (30) We used to use this on all sorts of repairs. The version we had set in about 1.5 minutes. This took about 4 hours, but it was still the same excellent result I used to get. I was delighted to find it again after all those years. Great product! I'm delighted to have it in my tool box. John
