New Surface Rust - WTF?
I live in MA and, as always, have kept my '69 garaged and covered all Winter. Never out in rain or salt. Took the cover off today for first start-up and noticed surface rust over many engine parts, mostly new ones, including air cleaner cover, master cylinder, dipstick, booster, ignition shielding bolts, and a few lines. Nothing major, but still concerning. I don't think the garage is excessively moist - actually it's a new home, although there is a pool next to it (outside) and some rooms below. Not heated or cooled. Wondering if this is a matter of crappy replacement parts or something I did wrong. Like I said, never happened before.
Any ideas?

Is you garage well insulated (floor, ceiling, walls and door) and is it sealed? Most surface rust is caused by humidity....moist air condescending on cold metal parts. Also unless you put down a vapor barrier on the floor moisture can come up from the concrete and cause surface rust.

A friend kept his pool chemicals on one side of his garage and his Harley on the other side. After last winter the front forks, wheels and a lot of the motor parts had corroded and started to rust. Keep your pool chemicals in a storage shed by themselves.

NEWS FLASH!!!!
There is water in the AIR!!!
If you don't want bare metal parts to corrode/rust, paint them, plate them or coat them with something that impedes moisture. I have done my very best to make sure that there are NO bare metal parts remaining when I refurbished my engine compartment.

WD-40 will help but you do live in a high humidity area of the US where 60% to almost 80% humidity year round. I live in Colorado and coat my parts down with WD-40 when I go to put the car to bed every winter and I am in an area that that generally stays between 15% to 40% year round unless it rains.

My brother-in-law had a new garage built last summer and he put a cover on his Vette. Fortunately, he went to show the car to someone and when he took the cover off everything was really wet under it. Needless to say, he took the cover off for the winter.

Condensation is one of the biggest causes. If the car is cold and you open the garage door on a nice warm moist day, the car and everything abut it will condensate and rust. I learned this the hard way with some tools in my garage when I was younger. Keep the doors closed until the temps are closer or the other way around.

you need a dehumidifier of some sort in there.Used to be a gizmo called a "Goldenrod" I think it was, was made specifically for vehicles stored under a cover to keep moisture out.

I don't think the issue is pool chemicals or lack of sealant, as the only thing different this year was the use of a car cover, which is supposedly "breathable." Ordinarily I do not cover the car as it does not really accumulate much dust. Just wanted to preserve the detail job.
I think next Fall the plan will be to leave it uncovered, possibly with the hood cracked slightly, and possibly the dehumidifier/dessicant.
Perhaps the lesson to be learned here is sometimes overkill can be the enemy.

I have used the car capsule the last 2 winters. I picked one up here from another forum member at a good price. It has a fan that keeps air circulating around the car. Second winter now and my garage gets very moist in the winter.

He is a great example. Back then I had just a pole barn, I walked in and saw the tires on my tractor dripping with water. I don't mean just moist, I mean water streaming off the rubber tires; but only 3/4 of the way up the tire. Those tires are filled with fluid for ballast and that fluid was very cold from the night before. That morning it was warm and humid out. The cold fluid caused the tires to condensate just like a ice cold glass of water.
The little warming rods and bags of desiccant will do NOTHING for you in such a large area unless you have the car sealed in an airtight bag.

I agree with everything the others have said. A new house could have greater humidity too. Concrete isn't a moisture barrier so any humidity coming from below will come straight up to the car. I'd store it uncovered with the hood popped up and see how that goes. Or, put a thin sheet over it, something that will allow air to 'breathe'. New plating these days isn't generally very good either.
Get a Relative Humidity sensor to put out there too and record your RH's.

Many years ago, at the GM plant where I worked, we were getting ready for our Christmas break. Some "whiz kid" got the great idea to let the temperature in the plant drop (a bunch) over the holidays so that a bunch of money would be saved from using less fuel to heat it. Since only the Patrol folks would be there, no big deal.
Well, holiday break was over and we all went back to work. Only problem...most of the expensive STEEL gauges and tools in the place had gotten rusty!! Yep, condensation over a 1 week period cost that "whiz kid" a job...and the plant a whole bunch of money to repair all those expensive tools/gauges.
