I agree with pretty much everything above. Lubricate the nipples when wheel building to help get appropriate spoke tension and minimise spoke windup. Once done they really shouldn't be coming loose if the wheel is well tensioned. I guess there might be some benefits to something like linseed oil which helps
stink the workshop out lubricate but then dries moderately hard - although not enough to make future adjustments a problem.
Am I correct in thinking Spoke Freeze is applied
after the wheel is built and so doesn't help lube the spoke threads when wheel building? Seems a bit pointless to me...
