If you choose to try us, Jig-a-loo, as part of your car maintenance routine, you can find out where to pick up a can here: http://www.jigaloo.com/us/e_store_locator.php. Here are 6 detailed steps and a few extra tricks for preventing rust on your car.

Step 1 General maintenance

a. Wash your car every two weeks; once a week if it is wet with salt on the roads.
b. Wax your car once every four months.
c. Keep the inside clean as well, being sure to clean up after any spills which can start rust from the inside.

POR-15 works better, its rust preventative PAINT...

[ac-dc]

These steps will not prevent rust, they will only slow down the process. This instructable seems like a shameless plug for the jig a loo product which is not a "rust-preventing spray" regardless of whether they market it that way.

You would have to spray it on displacing all water immediately, every time the car got wet, and that would be very costly and exposure to the ingredients bad for health. Any bare metal areas where rust would be a problem should be painted, and silicone sprays like jig a loo should NOT be used because they are difficult to completely clean off so the paint will adhere well.

would WD-40 work? random thought.

WD won't hurt, but it washes off/dries out after awhile. Boeing makes Boeshield T9, a spray that comes out liquid, penetrates, then turns into a waxy solid. Works real well, not cheap. Sprayon makes PDRP Waxy Film Protectant that seems identical but much cheaper. I've used both with success. You can even spray them into electrical connectors to keep them from corroding/oxidizing.

if you have rust on the out side check the in side the door and you will fine that there rust there too .check the drain holes in the bottom

[dll932]

Too true. rust tends to start from the inside or the bottom. It's important to wash the underbody more than the outside, and do it ABOVE FREEZING; salt won't do much below freezing or when it's dry. The worst effects are when it's wet and above 32F/0C. Besides, if you do it below freezing, your doors and locks will freeze.

it doesn't matter what country your car is made in, metal rusts. New cars don't rust because they are hybrid alloys. If your car is made before 1998, chances are it will eventually rust.

I drive an '86 pontiac bonneville (62K original miles) and it has rust, it adds character to the car.

That isn't entirely true. While all oxidizable metals will eventually rust, every steel-producing country produces a different quality of steel than others. German steel is very high quality, for instance, while Pakistani steel is of very poor quality and therefore tends to corrode much quicker.

[ac-dc]

Steel has iron in it, thus regardless of the quality it will rust unless it's stainless steel which nobody (?) uses for major body panels due to the lower strength to weight ratio.

What makes steel rust is exposure to the elements. High or low quality tends to effect purity and functional parameters, not rust resistance much. The *best* automotive steel will still rust if it is bare and left outside.

Water, salt, other chemicals and acceleration from heat. The far greatest factors for rust are whether the paint holds up, and whether the panel traps water/debris whether it be design or a clogged drain hole, weatherstripping no longer sealing well, etc.

[Project D]

Again, that isn't entirely true. German iron/steel is of an exceptional purity, so it resists oxidization much more than Chinese steel. Pakistani steel is probably the worst, I've had examples of their stainless steel rust in a matter of a couple of weeks. I learned the hard way to avoid knives made from Pakistani stainless. But yes, even the best automotive steel will rust if left bare to the elements. But that doesn't change the fact that steel from one country will rust much faster than steel from another.

Also, you forget the Delorean, every body panel was crafted from stainless. Too bad the car was a piece of crap.

80's Japanese cars are especially problematic with rust. Due to japan not having their own steel mills at the time and buying recycled sheet metal from the USA.

Buy an german car!

My dad's Mercedes rusted more in the last 11 years than my Alfa Romeo in 22.

[gafisher]

Corvette.

[neffk]

I have heard that there are problems with certain years and models. Someone told me that the sheet metal bodies used in the early 90s were particularly problematic because of the amount of chromium in the alloy.

[cristimar]

Japanese?

My damn handmade 1986 jaguar xj daimler rusted too :( And now they want 5000$ for paint :/ my city's climate is very salty and i dont wash and wax my car for a long time, if your car is in a good condition you gues that your car will never rusted, but they will be rusted :( thease are very useful tips. Thanks anyway. I am going to use thease tips for my other cars.

I really hate it when I see rust forming on the sides of my car. It really ticks me off. So I make sure that it is coated with anti-rust spray and I don't park my car outside the house when it is misty and humid.

I have 2001chevy 2500 pickup. have found that melt has to breath.If cover it with tar anything like it no good.

[iggy62]

what is the stuff have in it?

If locust beans land on your car they are vicious little things. Get them off immediately, or they will rather effectively attach themselves. Kinda like a tick. When the beans are stuck, if you try to pull it off it will leave a little bit. This bit will drop off on its own...taking most of your coating with it. I learned this the hard way with the locust tree that grows over my driveway. If you wash your car on Friday and one of these beans lands on it on Wednesday, get it off Wednesday, not Friday. By then it'll have found a new home.
