Corrosive-resistant finish for brass lugs in automotive environment

We have a BRASS lug which needs to carry 150 - 300 amps of DC current in an automotive (read: VERY CORROSIVE) environment.

What is the best finish for these parts?

We need to have low electrical resistance and high-durability both to salt-spray and handling (battery-type cables are attached to these, with compression washers - lots of friction).

We do already take sheltering proective measures (battery grease, rubber covers, etc.) but our customers' customers tend to abuse such measures, and we would like an additional line of defence for our product.

Thanks

Lead plating comes to mind. EN is a possibility, but probably not cost effective.
