The natural enemy of cars, especially old cars, is “rust”, isn’t it? If you want to ride for decades to come, you have to protect the body from rust. I often see that the license plate bolts are replaced with stainless steel so that they do not rust, but it is half correct and half incorrect. Every bolt has a nut. The combination of stainless steel bolts and iron nuts causes dissimilar metal contact and attempts to promote the oxidation (rust) of the iron nuts.

Bare iron bolts will rust quickly, so use plated bolts. The introduction has become longer, but I will explain how to protect the body. Apply the dissimilar metal contact described earlier to mount the sacrificial electrode. Simply put, a metal that rusts more easily than iron is attached, and […]
