Going to toss this tip in from my old days when I was glass bedding rifles...probably most of you know this but when working with epoxy if you want to mould it to something but want to break that bond when you are through...you use a "releasing agent"....actually a can of vegetable oil works just fine.

I see a use for that if you are going to epoxy in some tee nuts and are worried about getting epoxy in the threads....coat a bolt.... thread it up... and it will release after the epoxy has set.
