I see many clips on garage's comments. They say rust cannot be get rid off whether manufacturers dip the whole car in protection solution or not. Because these connection joints as in clips no matter it is bolt nuts or spot welding points, These joints could not be reach covered by protecting solution such elctro plating or hot dip galvanized.

@james_l4337 You cannot paint of treat car frames any surface process before dip in rust free solution. The whole body frame must be cleaned and exposed almost all its metal surface as much as possible before being dipped.

@james_l4337 I suggest you looking at this clip https://www.youtube.com/watch?v=uWfRPFneuYc minute 5.00 so on, He said you cannot get rid off rust eventhoug you dip the whole frame in rust protection coated because somehow those solution cannot reach to such parts or joints.
