I live about one mile from a paved road. It is called a gravel road but that is questionable. In the summer they put down salt brine on the road to keep the dust down. Generally 4 to 6 times a year is what the township likes to do, as a standard protocol. It is some times a lot more frequent say when the township is working on a distant road and they are using your road to move materials, suspect gravel tri axle trucks other equipment etc. That is great for keeping the dust down but it eats away your vehicles. He is the scenario. You drive on the roads during the day, summer time. Your car still picks up some dust. The salt brine does not eliminate all of the dust. Your vehicle sets outside over night and the dew settles on you car and activates the salt brine. 24 hour a day chemical attack. The worst thing to do is to drive on the road right after it has been treated with the salt brine, but you got to get home. It coats your vehicle with little gobs of brine laden mud. In a very short period of time, only days, that mixture will start to eat away on your vehicle unless it is completely rinsed off. After a couple of days those little gobs come off really hard. Then in the winter time the main roads are salted and some type of liquid chloride is also used. So there you have 12 months of chemical attach on your vehicles. I remember my first new truck. a 1978 Chevy .5 ton 4 wheel drive short bed. In 5 years living and driving on the gravel/dirt roads with that new truck the rear wheel backing plates had holes rotted thru them. I needed to replace the backing plates, wheel cylinders because none of the hardware would break loose, lines and mounting bolts, the U-bolts, nuts and retaining plates for the rear springs. In my garage I keep a small supple of brake line fittings, a role of .19 and .25 brake line, a couple quarts of brake fluid, etc. My brother in-law still farms. He purchased a new chopper box, New Holland, back in the early nineties. A chopper box is only used for maybe at the very most 3 months out of the year but probably much less. This summer I had to replace the rear axle struts because they were almost completely gone/ rotted away. My 2010 825I Gator with 3900 miles is looking a little rugged underneath even though I keep it reasonable clean. Just a FYI on salt brine. Later.
