The Animal had a compound finish on it, so most rubbing compounds should get you close. Clean-n-Sheen would be a good place to start, I think that's a compound polish. Storm Step 1 and Brunswick's Rough Buff should work pretty well, too. Some compound polishes finish to a higher grit level than others (Step 1 finishes to 800 grit, Step 2 to 1500), so if you want a heavy-oil ball when you're done, stick with the lower-grit polishes like Step 1.
