Wiper Arm Corrosion - constant problem Aussie Fords?

[Dr Terry]

This happens with most cars, I'm not sure if it's salt corrosion (close to the coast) or if it's left out in the weather all the time, lack of regular wash & polish or whatever.

I buy & sell cars & I remove, bead blast & then repaint the wiper arms on just about every second car I get. Japanese, Euro, Aussie, Yank doesn't seem to be worse on any particular brand of car.
