I use superglue, but after a while in the water, say 5 nights or so, it starts to degrade and I have to re-glue it.
maybe zap a gap is more waterproof?
thanks jfig and rock for your speedy responses, as long as it doesn't weaken the knot, i'm ok with having to re-glue them, i'm sure by then i will have found the zap....thanks again.
