Talk about a generalized statement. Sure, the body may not develop cancer, but engines, undercarriage, fasteners, etc will end up looking less than stellar. I saw an 80's Carrera today in Pt. Loma. Looked ok from down the block, closer inspection showed it to be just another beach bum. I'd think the East Coast might be worse.

Ocean front summer home in CT for 10+ years, zero humidity issues or salt / film on anything stored in the garage including various Porsches, scooters, etc. PM me if you'd like to compare notes.

In those 10+ years of being there constantly all summer long there were maybe 8 or 9 times when humidity got to a point where we closed the windows and turned on the AC.

I suppose it all depends on where you are, prevailing winds, etc.

I live on the Jersey shore between the bay and the ocean year round. We have a heated garage but even when I still had my Porsche, it seldom got in there. As others have said everything takes a beating here from the salt air. I never have had any real problems though on any of my cars that I would attribute directly to being here. I would hesitate to have a car here though that was not a daily or at least frequent driver. Cars, bicycles, boats all seem to do better here when they just don't sit.

I agree with Ron about location and prevailing winds. On the south coast of Nantucket the windows would cloud over EVERY day with salty film. of course, that house fell into the ocean a few years ago.
On the north shore of Boston it's not nearly as bad. I think a well sealed garage with a dehumidifier is all I would consider, unless you want to own the car forever. Isn't NYC surrounded by mostly salt water?

If you wanted to really go for it ! Insulate the garage with spray foam, walls and ceiling.....have some floor covering that will not condensate in cold weather and helps to reduce condensation from concrete slab., Good garage doors with "tight seals", heat if possible.

The spray foam will not only insulate but act as an air barrier, seal sole plates to concrete floor with sealant. ( test for air leakage if required )

Good Luck

JP's comments mirror my own experience. My daughter lives in San Diego and her cars have all shown signs of increased oxidation event though they are garaged. My son lived in Pismo Beach for 2yrs. and the aluminum components in the suspension of his 300zxTT had visible oxidation. There is a lot of aluminum under our cars. I would do all I could to protect your car from the marine environment.

I thought the 400 lbs of cosmoline protected everything from EVERYTHING?

Come on now, let's keep things on topic. The OP asked a legitimate question. Cleaning up the mess...

NC TRACKRAT

There are MIL-Spec corrosion-inhibiting sprays that can be applied to the vehicle that would be less noticeable than our arch-nemesis Cosmoline. It would be a good idea to treat exposed suspension, fasteners, hinges, latches, engine compartment, etc. to minimize "canker". Fastidious washing and waxing whenever possible would be a very good idea. Important to remember, as mentioned by others, corrosion thrives on salt, moisture and heat.

I've lived in CT my entire life and summer there every year. There is more corrosion / humidity damage happening inland than there is on the shore. When it's 95 degrees and dripping-wet humid inland it's 85 degrees and dry with a sea breeze down at the shore. My things in our house and garage at the shore take much less a beating than my things back inland. After a storm I have salt spray on my windows and siding, but not a bit of moisture in the house or garage. There's a big difference between salt damage because one drives their car in the winter in CT vs. having a car down by the ocean during the summer.

My Grady White on the other hand does put up with a lot. After 8 years it's showing some pitting in certain metal parts. That's a boat that lives on the salt water and is used often.

Just try to keep things in perspective and understand that everything is local in nature. Our climate in CT may be very different from others.
