NICE fly! I can imagine what it will look like with H20 added.
How do you like the devil's sauce vs. softex?
I've been pleased w/ softex for baitfish heads unless the buildup characteristics of epoxy is necessary like when using fat plastic eyes, etc. I've never have problems with losing flat sticker eyes or breakage along the materials / back / sides, even when used to permanently lay (laminate?) flash, angelhair or other materials against ez-body mesh for sand eels or to form a flexible "head" on juvies, etc.
One problem I encounter with it is that the jar can become impossible to open sometimes, and the toluene (common to both) is nasty stuff from what I understand.
