I smeared a *tiny* amount of Nevr-Seez on my bleeders. I also have all 4
rubber dust boots for them; it helps keep gunk out of the bores.
Nevr-Seez is an emulsion of aluminum particles and heavy grease (it's
silver, and gets on everything- I dabbed a bit on a rag and wiped it over
the bleed threads)
You can also get copper-based stuff, usually sold as "Anti-Sieze Compound"

Frankly I wouldn't use Coca-cola for dissolving battery corrosion; it is
best to mix up a paste of baking soda and water and scrub that on with a
disposable paint brush, then wash away with lots of water
Battery corrosion is acidic(sp?); baking soda (Sodium Bicarbonate) is
basic; the mixture of acid-base forms a gas and a salt- hence the "lots of
water" to remove any traces of salts left on your metal
Coke has phosphoric acid in it, so it's probably the bubbles in it that
remove the corrosion, more than the chemicals
There are hundreds of different things to use to remove stuck bolts. My
favorite is Tabasco sauce, because it's cheap and won't poison you (but it
does burn!)
