Definitely agree with the latter assertions about the filiform being surface. On a car, it is usually from within but I have yet to see a bike frame come from within. Usually it is the result of a bad primer adhesion or a pinhole nick in the paint protection that allows the moisture or corosion process to wick along under sub par finish.
