The main thing I don't like about the Gel is its viscosity. Having spent half of my working life in a custom wooden boat shop, and in my own shop, I have forgotten how many 50 gallon drums of epoxy we went through. I know from epoxy- but that's not to say that I can't learn some more. One thing I do know is that a better bond to wood will be effected if the wood is wetted out first with un-thickened epoxy which will soak into the surface better than thickened stuff will. Then, stir in the thickening agent (I use colloidal silica- the same stuff that people assume is "fiberglass" in the Brownell's kit) and proceed with the bedding/repair/glue-up on top of the wetted surface(s). This isn't germane to the question at hand re: filling a crack, but is something to think about when doing other projects.
