In my neck of the woods, I wouldn't touch a car without some form of rust protection. Not only because the roads are saltier than MacDonalds fries, but there's a load of salt in the air just living close to the ocean.
Case in point, our last house was about 1 mile from the ocean, and the salt in the moist air was enough to form rust on my hog after being left out for only one week. Since we moved inland 30 miles, the bike sat out for over a month and- surprise- no rust whatsoever. So it's not just the road debris that chews up cars, but what's in the air as well.
Maybe someone can clear this point up tho- does current rustproofing give any sound insulation like the older graphite or wax undercoatings? My car was undercoated before I drove it, so I wouldn't notice any difference anyway - and like many of my fellow bullitheads, I usually drive with the windows down!
