iowa/sd/ne same way and thats where my monte has lived its life till i made the big move

Every car/truck i own has factory lines on them. So it isn't a Dodge thing it is a salt thing :!:

I dont notice a difference between any makes, salt eats them all.

WTH hell you putting salt on brake lines for?. Salt goes in your grits or on french fries. Sorry Mopar, couldn't resist.
Glad you got 'em going with very little cost.
