best surface to park car on long term?
 

I have two cars, one inherited, the other a long term project I won't be getting to for a while. There is space in the yard to park them nicely out of the way and basically out of sight. Its a dirt/moss/grass surface.

Can anybody recommend a good cheap way to prepare the surface to park the cars over? I don't want to park them on bare dirt and grass for rust reasons, I was thinking about buying some gravel or plywood and making a space, any suggestions?

The idea is to try and keep the rusting down while they sit out there.

Gravel would be ok, or, you could just lay a tarp down. Spray the under side of the car with wd 40 or some other water repellant.

get a few jack stands and let the car sit above the dirt, that way you wont get a flat spot in your tires etc

Put 3-4 inch's of gravel under the car, you have to keep the moisture away.

Gravel over dirt wont keep the moisture away. Cheepest way is to buy a roll of visqueen(plastic) park car on top of and weigh down the edges. I've parked on gravel over dirt before and it does not block the ground moisture.

I agree--use polyethylene sheeting to prevent moisture from the ground affecting the car.

Its cheap, quick, easy, and it works. If you'd like to spread some gravel on top for aesthetic reasons, go ahead. If you do that, you should use at least 6mil poly under gravel.

great suggestions thanks!

On the ground DUH!! :D:D:D

You get lots of rain/snow? That will mix with dirt, leaves etc. and end up molding on top of the tarp, so be sure to wash that off regularly or it will be just as though the car were on the ground. If you can keep people (particularly little kids) away from it, consider setting it on concrete blocks so it's up some, that will attenuate the moisture issue.

Ixnay on the plywood.

Use a load of large crushed rock trucked in.

As time goes by, the crushed rock will be consumed (covered) by the grass - but the subsurface will be an acceptable parking surface. Keep this area mowed short!

Try to make sure the car cover you use is water repellent. Some of the cheaper car covers just soak the water up and let it get to your car's surface.
They make water repellent car covers with downward facing vents to promote air flow to some extent as well. Nothing too fancy, but could reduce or eliminate chances of surface rust forming, etc...

also be aware of mice. they love to live and chew on long term stored cars. I store my car inside an attached garage so I havent had any issue. but I always flip down my sunvisers as it is a perfect perch for chewing the headliner. metal jackstands and remove the tires makes the most sense to me as it limits their access a little better, and if you can crawl under and stuff any openings with stainless steel or copper wool. car covers are a toss up for an outside stored car, they can blow in the wind and any dust that gets under will act as an abrasive.

In a barn with a wood floor. Hands down the best unless you want to spend a fortune on climate control. The wood floor should be at least 18" above the dirt or gravel.

I have seen a great many cars come from wood floor barns and look new underneath. But I have seen cars on concrete with plastic and they still rust because the moisture can still float around the room when the concrete sweats.

Hrmm I wonder if you got a giant foodsaver bag and just vacuum sealed the car in a giant baggy. haha.
