The thing that I understand with epoxies is that they should ideally be cured in a hot box as it creates a stronger joint and since the glue begins to soften at the temp it cured at. (ie; beware hot cars)
Snakeskins will work fine over the boo, but you'll have to scrape the rind off of it. Glues tend not to stick to the waxy rind. I'm finishing a bow now, in fact, with snakeskins over the boo.
