From what I have read about water curing the THC will not degrade and there are not enough trichomes falling off to be worried about. In fact, because your THC is suspended in water, the resin will break down much slower than in air. Remember: Air and heat degrade THC. The trichomes on the inside of the buds are what you should care about. The outside of your buds will get rubbed off whether you like it or not, by bags or jars or whatever you sit it in/on. THC is not water soluble which is why you cannot make tea infusions effectively with it. I will be water curing soon and I have faith that it will produce a much smoother smoke with much less chlorophyll than regular bud.
