We often go to Nagano for skiing in winter by car. The northern part of Nagano has a lot of snow fall in winter. We need snow tires when we drive on snow roads. On the other hand, Nagano prefecture sprinkles snow salt like calcium chloride on the road for slip prevention. However, these snow salts make rust in cars, especially underbody parts of cars. Actually, I have a car and it's a sports utility vehicle, so I put antirust paint under my car. This rust paint is a good agent but is kept for just one year, so I have to reput these paint on my car every year. I think it's the best way to keep my car in good condition.
