Raise car BY SYSPENSION. This still raises the car off the tires, but the struts/shock shafts are not left dangling at full travel. The shafts of the shocks are not exposed to the elements either.
Raise the car as high as you can. The moisture is more closer to the ground (like fog). If you have the car indoors, then lay newspaper under the cr, and place a sheet of plastic over the newspaper. The paper soaks up the cement "sweat" and the plastic keeps it off the car.

Stabil is fine.

DONT stat your car once a week. The moisture is worse for exhaust. If you must, start it on a warmer day, once every few months. Let it run for a Loooooooong time, like 20 MINUTES. Make sure the exhaust tip is hot to the touch. Then the loisture in the exhaust will evaporate.
Battery trickle charge once every 30 days is enough.

Thats about it for now.
