Condensation getting on car in garage. What do I do?

[sixpack_sid]

I have my resto 73 Charger stored in my Garage. It is a 24 x 24 pole barn with 13ft ceiling. It's a 2 car garage w/concret floor. Everytime it rains, or we have wet weather, I notice the chrome on the wheels and the chrome valve covers has condensation on it. The chrome parts on my motorcycle in there are wet too.
I also have a 2 car garage about 5 ft from this one with 8 ft high ceiling. There is no condensation problem in this garage. It's the same construction.
Any idea what I can do to stop the condensation? I'm worried it's going to rust my chrome!

Maybe a stupid question , but is your barn vented?  I had a BIG prob in my garage a few years back. One roof vent and the condensation went away! Although I still run a fan on really humind summer days....

You could always stick your car in the other garage...

I bet that water is wicking up through the concrete.  Maybe if you sealed the concrete floor with something it would stop?

How bout a dehumidifier. Just make sure you do something, I had the same problems in my old garage and it really made a mess of my new brakes, wheels, and the paint on the underside of the car.

I'd try venting it first.  If you don't want to seal it right a way,  cover the floor with plastic and see if that makes a difference.  I

cover the floor with plastic than go out curb hunting and fine some old rugs and put them down on the plastic.do you have a steel roof on the garage?if you do they sweat and drip on the cars

Just wood and shingled roof. The floor is always very dusty. I don't know if it's concrete dust or what. The floor is not wet though.

You said it is a pole barn.  Are there sides to it.  Only reason why I am asking is that I know pole barns as being poles supporting a roof structure and thats it, no sides.  If you have no sides, chances are you are never going to be able to do away with this problem as it is not able to have the environment somewhat controlled.  If it is an enclosed garage, you might want to try using a dehumidifier.  I had moisture problems in my garage under my house and as soon as I got that, the humidity in the garage dropped almost instantly.  No more "sweating" of parts on the car.  The reason you are getting moisture collecting on your car is that the parts on the car are colder than what the outside air relative humidity is so then the air/moisture condenses on the cooler parts forming "sweat".

Metal roof and side pole barns have a tendency to sweat more - but not an issue in your case.  It sounds like this barn is tighter than your other one.  (The temperature can't equalize quick enough - as per resq302).

resq302 is correct, the dehumidifier would do the trick.  It will also do the trick on an electric bill.   Do you have a ridge vent, vents along the soffets, peaks, etc?  Is the building heated? (sometimes?)

If it is vented, hook up small fan in the peak to blow air out.  See how it does.

There's always going to be a couple of days a year it will sweat but if it's not heated, not metal, and not sitting in a swamp, you should be able to handle it through ventilation.
