I am not soo much worried about the Corrosion (I clean it regularly) as I am my tire actually getting through the layers of salt and actually touching the Pavement! MY blacktop road is actually totally covered in Salt and Sand. (town guys are insane)
I will be trying the S100 Corrosion Protectant for sure!
I agree about the over zealous government workers over salting the roads. Fortunately I don't have too many of those people around where I ride - BUT - the intersections, that's another story. I think they think that intersections are for dumping their load before going back to the barn.
I think you'll like what S100 will do. I spray it on "all" metal parts (except the rotors of course) and especially all the fittings. You can buff it if you like the clean look. I don't really care - I just spray it on and leave it (less work). Don't really care what the bike looks like during the winter.
