I must say Rust Belt Pete, you nailed it. I live in the Hudson Valley of NY. Did you know, the state DOT changed the composition of " road salt" in the 2000's ? No more regular rock salt, not good enough. It all goes by temperature now. The colder it is, the more corrosive additives they inject into the mix to stop re-freezing. That's why the roads stay white for weeks after a storm. I had to take my 13' CRV off the road due to frame damage from this stuff. Shocks/ struts/ asphalt are no match for this highly corrosive concoction they are throwing down on the roads in the winter. I don't care what brand you put in, it will eat it up in no time. I'm constantly re-painting frames, brake lines, fuel lines, even stainless steel exhaust systems. Fortunately, I'm retired. So I just have to do salt maintenance on the wife's car yearly, for another 9 years. Then, she retires, and we leave the salt belt forever !!!!!!
