Thanks bro, that was exactly what I was thinking. A fan perhaps? There's a plug inlet off of the concrete pillar on the drivers side. Air movement would definitely alleviate the problem but I wonder if the other tenants (who pay $2700 a month, renting) would be amenable to a fan running constantly for four months under my car on their dime ;-) I'll come up with something, maybe a barrier to keep the water from my friends car from trickling down under mine. Rust hasn't reared it's ugly head yet in the two years I've been storing it this way but I'd like to do anything I can to prevent it obviously. Hoist lifts have shown nothing in the way of any rust but I'm pretty **** about my cars...

 

+1 on sta-bil fuel...

i over inflate the tires and also park all 4 tires on small pieces of carpet...
as far as the cardboard underneath... how about driving the car onto a large tarp ? is this the same idea, thats what i do at least...

 

Yes, the tarp is fine. The intent is to provide a moisture barrier between the tire and the concrete. Over time, the concrete will accelerate dry rot of the tire.

 

Yeah probably not a good idea. I would just lift the edges with bricks at the corners and place another brick on top to hold the plastic barrier in place the whole time. I would suggest 2x4's but it will absorb water and bricks are a better way if you can. Also another idea would be to use the 2x4's on the cement and the tarp lifted on the edges all the way around with bricks holding the raised edges of the tarp on top....hope it helps

 

Brilliant! Thanks man, I have a tarp and my father has spare bricks so I'll set it up this weekend. Thanks for the info, much appreciated.

 

Anytime and I think that will do the trick for you.....

 

One of these may be a viable option for under the car. No noise (like a fan would produce), and cost effective. Having a cover over the car my be an added benefit, as long as the cover breaths. Basically, a heated rod:

Assuming they'll allow you to run power, a 25 or 40 watt light bulb will do the same thing.

 

Very true, but the glow from underneath will let people know it's there. So would an extension cord for either device. Just brainstorming. No offense.

 

None taken. But I believe it's being stored indoors but where water tracked in from other vehicles also stored there can cause water runoff.
