HELP - RUST - CORROSION - WHAT TO DO

[amalventano at sc.rr.com (Allyn)]

ok, i've got some major salt corrosion _everywhere_ on the passat. a/c
lines, fuel lines, screws, bolts, everything. the body itself isnt bad at
all, oddly enough. what can i use on the various metal lines to convert the
corrosion to something more metal-like. i fear that if anything pits any
further, im gonna be leaking everything - all over the place. so... whats
the best rust-converter-stopper type stuff?

side note: anyone got a b3 passat condenser? mine is leaking in 2 (yes, 2)
places. it appears to have rusted through where it meets the radiator.
