We moved into our new house a few months back, and I promptly filled both garage bays with my tools. Now, as spring approaches and I'm itching to spend more time out there, I'm noticing a lot more rust showing up. My previous shop, also in a garage, had no moisture problems at all - unprotected cast-iron tabletops never showed any rust at all. Now my drill press table is covered with a layer of rust. No pitting yet, and I'd like to take care of this pretty quick.
Garage is a standard two-bay deal with two aluminum overhead doors. Floor is concrete, that appears to have had a second layer poured over the first, but in any case it's in lousy condition - full of craters. The concrete seems to be pretty low grade stuff - it chips easily, and sounds sorta hollow in several places. Walls are concrete block to about 3 feet with some cracks, and unfinished two-by above that. The rear wall is partially below grade. The front is obviously at grade. Siding is board and batten. Ceiling is open to the trusses. Overall, the structure isn't particularly tight, there are some visible openings.
Questions: 1. I'm not sure if fixing the weatherstripping, trim, etc. is a good idea or a bad one. If I make everything tighter, will I just be keeping more moisture in, essentially creating a big sauna?
2. I'm thinking about putting in a plywood floor over 1x2 or 2x2 sleepers, as the underlying floor is pretty trashed. Will this help with moisture problems?
3. Ideally, I'd like to also finish the walls to some degree. As it's a shop, I think I'd probably want plywood walls rather than wallboard, so I can attach whatnot to the walls without really worrying about it. Is this a bad idea? Should I go with wallboard instead?
4. Like many folks, I've got a couple of tons of crap stored in the rafters of the garage. From a moisture control standpoint, how much should I worry about the open ceiling?
