All these videos I have seen are US vehicles and usually it is the steel line that is rusted out and leaking. Here in Australia we don't have that issue because we don't generally have snow in winter (Alpine regions excepted) Plus, I noticed lots of rust elsewhere uinder the vehicles which looks bad. Vehicles here rarely get like that. Just think you guys in the states have a rough deal with your cars rusting out so quickly and badly. Just sayin.
