My garage is too humid. A big part of the problem is (I think) sometimes parking a wet car in it, with the moisture having no where to go except rusting up my tools. There's no ceiling cavity so a DVS/HRV/Smartvent style system isn't going to work (much less be able to be justified cost wise to Mrs MDF). Instead I am thinking about adding some bathroom style fans at each end on the gables.
1. Will this help? Enough that it actually is worthwhile investigating further?
2. How should I run the fans? Both blowing outside air in, both blowing inside air out, or one of each? I was inclined toward the latter to get air flow going but clearly that will only help to the extent that the outside air is dryer than the inside air. So perhaps some kind of humidity differential monitoring will be required?
