to protect from salt try any or all of the following:
--Rinse,wash or wipe down your bike after every ride, (drip water from above to avoid squirtng into bearings)
--lube/grease both the surface of all parts and threads where "inserted" or attached to the bike and the bike itself at all contact points; i.e. the seat tube and seat post. It's a good idea to grease all (bolt and nut)threads and contact points except the Bottom Bracket Spindle flats, Crankarm flats and braking surfaces.
--check regularly for paint scratches and chips and "touch up" as soon as possible
---Coat the inside of the frame with some type of rust retardent, remover or or barrier- even WD-40!, (I don't know how long WD-40 will last though), it will purge the water. There is some aerosol stuff made specifically for bicyles, it's a name like Weigle, Whitter etc, your local bike shop probably knows about it. You might try a car engine storage spray, it's used to coat the insides for long term storage to prevent rust.
