[Public-List] Cutlass Bearing Flange Alberg 30

"Is crevice corrosion only a problem in salt water or can this happen

It happens in fresh water too - even to bronze and particularly to SS

I can show you the bronze bolts I took off the centre rudder strap on 
Sunstone 10 years ago - when she was 30 - 50% eroded.

Best

John
