Here is a great head cement recipe. I'm not sure where I got it, but I use it on almost all my flies as a head cement, and use it where ever I would use epoxy. In a small jar mix 4 parts houishold Goop® and one part toluene (you can get it at Rona, Home Depot, etc. for about $5 for a quart). Mix them together and seal the jar. I bought a cement dispensing jar with an applicator cap at Sea-run. The mixture should be about the consistancy of pancake syrup. Apply as yo would any other head cement and allow about 5 minutes to dry. It leaves a hard, glossy and somewhat flexible coat. As I said I use it now anywhere I would epoxy and have been totally satisfied.
