You might consider pre-emptively replacing plated steel hardware with stainless (corrosion-resistant, actually) steel. I'd suggest using Tef-Gel (http://www.tefgel.com/) on as many dissimilar metal joints as you can; bottom bracket, pedal threads, stem, bar, seatpost and other clamp bolts and so on. It is designed to protect against corrosion in marine environments. I'd suggest using stainless pedal washers also. Framesaver as suggested above or the Amsoil equivalent are highly regarded. There is a new rust-preventive lubricant from the inventor of Tufoil which has gotten good reviews: http://www.hinderrust.com/about-us/ Use stainless shift wires or at least replace galvanized ones with stainless when (not if) they rust. Keep your chain well lubed with a wet-type lube. A good coat of paste wax will help preserve the paint; washing it with fresh water will help flush away salt deposits.
