No sir, the underchassis itself (frame). That part where the "hole" is. One of my officemate even an undercoating but to his surprise, rust had started to form. According to them, you have to feel your way around the area as the rust is not visually noticeable. The guy who first noticed it said that the rust started around the "hole" area then eventually spread to the point that the area where the chassis no. is stamped got to be so thin.
Sir, I was referring to the JDM/converted units. Not the local units
