I live near the Northsea Netherlands - quite damp as well, though the GT is
always parked into the heated garage when not driven.
Anyway the silicone fluid is in for many years now (8+ I suppose) and
there's no sign of water.
Perhaps the plactic brake fluid cannister of the master cylinder of my '71
model helps here.
Cheers,
