I build with sapim alloy nappies a fair bit and I can assure they do seize eventually although it does take alot of wet weather riding. If you use an anti seize compound or sapim nipple freeze (a week loctite) on the threads then this maybe avoided but as I said is the trick is to build a wheel which is stiff enough with good even tension that it never goes out of true. If you do this you never have to worry about the nipples being seized. Brass nappies can become difficult to turn on wheels ride in lots of wet weather but that is more grit in the threads rather than corrosion. The effect is the same though.
CleanING the wheels after you have ride on gritted roads may not help as the salt solution has got into the threads and you won't wash it out. Also oil dropped onto the threads will not get into the threads. When building if I find a nipple that it tight to turn dropping oil onto it does not help. I have unwind it and oil the threads then screw it back on.
