Very nice jigs, what head is that? As for thread finish, I use either Loctite super glue brush on when using silicone or rubber skirts and I use Sally Hansen's Hard as Nails clear when I tie hair. The main reason is the clear nail polish leaves a very visible white residue when it dries on silicone. The Sally Hansen's brand clear is what I prefer, it takes a little longer than other brands to get hard so it penetrates deep and so far I haven't had any thread failures.
