What I did when I first got my VW and noticed a bit of rust under the battery was clean the rust as much as I could with a wire brush, then I used some phosphoric acid to convert the rust to iron phosphate. (I guess I'd use POR-15 now). Then I rinsed with some banking soda and painted the area with a few coats of epoxy black enamel. Then I bent a tray out of some galvanized steel figuring if batteries did leak it would be easier to replace a removable tray than the pan. I lined the bottom of the tray with a couple sheets of regular cardboard that I had soaked in baking soda and let dry. Since then I haven't had any leaky batteries though, so I don't know how well my idea worked.
