I phrased it wrong. What I meant is it's not water soluble to the point where you just wet your car and it'll all dissolve off.
Well, that's because it's "road film". As Mike Phillips has noted, and I think I mentioned earlier in this thread, whether it's just rain during the summer, or snow mixed with salt, it also mixes with all the oil, trans fluid, coolant, gasoline, tar, Starbucks, etc. that's on the road.
