Dr Tax, are you sure this is an issue?

Are the lawyers where the problem is?

I did a little looking on Yahoo and found many links to site that basically say the mold thing is a scam. As I pointed out, why is it suddenly a concern. It never was when I lived in Houston.

Is what you need a way show some form of reasonable countermeasure to mold growth during construction so as to beat off the lawyers and get a better insurance rate?

Look we fight it, in medical construction, but of over 2000 kinds of mold in this environment, TWO are toxic. The rest are just unsightly.

We use Clorox. Haven't lost a paying customer yet. .02

The new 360s don't rust at all, they "oxidize" LOL!

Don't drive it in the rain. And if you happen to get caught, be sure and wash and DRY it thoroughly (especially underneath) when you are done. I know some here have said they use their leaf blower in the engine compartment after a wash to make sure and get all the water off.

Leaf blower sounds interesting, - it's hard not to get caught in any rain here in So. Florida...

Its all a question of removing moisture from your storage area. You need to either condition the storage location or make provisions for dehumidification. You can either purely dehumidify via mechanical means, or use an air to air heat exchanger to recover the energy spent cooling or heating the air in the garage. Our firm has designed and implemented many systems like this for collectors garages. They're not that hard to do, they just have to be properly engineered.

Remember that energy (heat) and moisture will always move from an area of greater concentration to one of lower concentration in an effort to equalize. So in general in a hot, humid climate, heat and moisture will try to move from outdoors to the relatively cooler,drier indoors. Wherever the first point of condensation is is where that exterior moisture will accumulate indoors.

If you have a very effective thermal and vapor barrier in your exterior wall construction, you should be able to keep the moisture out. As far as ther humidity in the environment you will be driving in, the car itself should always be at a temperature equal to or higher than the outdoors, so moisture shouldn't condense on it.

Interesting, thanks for posting… Can you direct message me or recommend a set up for my garage ? Thanks so much

Sean, do you do residential design? I have been told that if I install a dehumidifier in front of the return air that this would result in a big drop in humdity, all other things being equal. Have you heard of this?

Holy thread revival!

I use a stand alone $200 dehumidifier plumbed to drain outside so I don’t have to empty the bucket, teamed up with a mini-split air conditioning unit. It easily keeps humidity below 50%. You know where I live, so that’s pretty impressive. It defeats critters too because insects need humidity.

I live in an extremely humid environment...have my Ferrari for over 15 years, no rust. Rain and salt cause rust here, not humidity.
