I agree with the epoxy kit being a waste of money. Save your old plastic lids from coffee cans or margerine tubs, you can mix epoxy on them then once the excess is cured, bend the lid and the dried epoxy pops off.

I grab coffee stirrers from places to use for mixing and spreading, wooden ones are best and you can usually break them in half.

Don't use 5 minute epoxy for things like stabs and holding wing halves together, it's not strong enough.
