I'm with James on the 60 minute stuff... I'm just too slow for anything else. The 60 minute Devcon gives me time to mix it and let it set next to me while I tie up about a half dozen to put the epoxy to. Generally I'm too impatient to mix the epoxy last because I don't get it mixed well and it doesn't set up well... so this is the way I have to do it. Then my fly wheel is filled with hooks and drying all night and I'm happy the next day.

On another note: I have found that I have trouble with yellowing with most all brands of epoxy that cure in less than thirty minutes. The thirty minute Devcon is usable, but starts out a yellowish clear and stays that way. One hour Devcon is the only thing I use any more, mainly because of the clarity when it dries and the ability to get the bubbles out of it when applying.
