I bought some of the Bondic resin to try and it's pretty expensive compared to some of the brands that are readily available. For .14 oz it is $12. That being said, the little light is pretty impressive even though there is a fair bit of tack on the resin once it cures.

In regards to using resin on a parachute post, I'd be afraid to add weight to my dry fly if I were tying a sparse pattern. I prefer the super glue method.
