[1928Mik]

My car has always had rusty water, even before it's light restoration in the early 80's. After it's 30 year hiatus my Dad put it in without draining fluids, I completely flushed it before starting in 2016 and use distilled water and green antifreeze with some rust inhibitor. Rust is still present but does not overheat like it did with straight water. Every winter I drain it too. But since it seems to be a non-issue I just run it.
