Richard, there is an access panel to the battery on the rear vertical bulkhead. You can see it if you take out the bulkhead/parcel shelf carpet.
The inner wheel arches are alloy and are not coated with anything internally at the factory. The outer will be covered with underseal. You could drill and bolt an alloy plate over the hole.
