In result, my discs were fine and discs on my wife car were wrapped again. After I resurfaced discs on her car I told her to do same thing when she stops.
Since that problem is gone. I didn't replace discs. They still the same.
Of course it depends on disc's quality. If it's an aftermarket junk nothing will help.
Also, I thought that puddles might be a reason of wrapped rotors.
