Hey folks,
I've been debating whether or not I should get the car undersprayed with oil. When I crawl under the car when up on jackstands, there is PLENTY of surface rust seen everywhere - frame rails, floor boards, etc. I just had new struts put on and the old ones had to be torched off because the rust had developed so bad that it looked like the metal had just 'melted' together. (The new struts are disappointing by the way - the car definately rides more smoothly now, but EVERY little bump on the road sounds loader and rattles the car more than before.) Living in Canada is hard on the underside of any car, and mine has never been oil sprayed, never had any Ziebart or rubberized coating applied and it shows. I'm guessing the damage is already done, so is there really any point in getting in oil sprayed now??
Cheers

I have NEVER heard of oil spraying anything other than the street!

What on earth do you spray it with? 10w30? *chuckles* I've got leaky seals just for that reason!

No, really, I've never heard of it.

It's a cheap and effective way to rust-proof your car. It's been around for at least 30 years here in Canada to fight the effects of salt applied to roads in winter. It's not the same as the rubberized protection some dealerships offer to new car buyers, and it's not the Ziebart thing either. Many auto shops can get a licence to apply a special kind of oil (and no, not 10W30) to certain parts of the car that are prone to rusting. There's a chain of stores called Oil Guard (I think ... ? ) that focuses exclusively on oil-guarding cars. They take your car, drill small holes in the rocker panels, door frames, maybe the trunk area ... etc. and spray in a fine mist of oil to all metal parts. Costs about $100 per car. The idea, of course, is to protect the metal on your car from being exposed to water, sand and salt which causes rusting. As far as I know, there are 2 kinds of oil they can apply - a 'drip' formula, and a 'non-drip' formula. The non-drip kind (thick oil) is usually applied on newer vehicles, say 2 years old and younger, the other 'drip' kind (thin oil) is meant for cars 3 years old and older. The main difference between the 2 kinds of oil is their ability to 'creep' along small cracks and crevices in the car's structure. Older cars probably have more cracks and crevices in them so the drip oil is used to creep along slowly to get into all the cracks of the car. The problem with the drip oil is that it will totally screw up your driveway - or wherever you park your car at night - because, as the name implies, it drips! The dripping stops after about a month and leaves a nice rectangular box on your driveway outlining exactly where your car was parked! My neighbour did this to his car and he now has the rectangle on his driveway and probably wont easily come out.

I'm trying to figure out if there is any point in applying the oil to my car even though it's already fully rusted underneath and the damage is probably already done. The best thing to do would have been to apply a coat when the car was new and then maybe another coat 3-4 years later.

It's suppose to be an every year thing.

Park on the street after doing it Dave, I worked at the one on Dundas E back in the day!

You know i feel your pain. I lived in the north for 40 years and i had to put up with rust from the salt they put on the roads. I now live in the south and my 10 year old intrepid has no rust at all under neath. No rust on the the doors either. But i hate it here because its so damn hot in the summer and believe it or not i really miss the snow. If the rust is that bad maybe considering getting a different car.

It must be... I've lived on the east coast (NJ), and mid west (IA), my wife is from North Dakota (2 hours from the Canada border) and she's never heard of it either...

MUST be a Canada thing... eh?

I did my truck just before winter. Picked it up from NC rust free, dont want anything to form. It collects a helluva lot of dirt, and thats what you want it to do, an effective barrier that will never rust. Oiling also stops rust in its tracks..as long as its not too bad.

If you really want to get technical, its a good idea to spray "pocket areas" like the inside bottom of your doors, and inside your rocker panels if there is access....basically anywhere water/salt/crap will collect and form.

Lightweight oil in a garden sprayer works well, stay away from hot areas with it, or you will smell nothing but.

Definitely a "rust belt thing"...lol...I never knew about it until someone from northern Michigan informed me when I asked why the underside of their car was so filthy.

You have to powerwash the heck out of it in springtime.

I did my 88 toyota pickup also after I restored it, and those are known to be one of the worst rusting vehicles.

with out a hoist, how difficult is it to effectivly hit things under the car? If doing it yourself, what do you spray on it for oil?
When I had my shop, I used a pump jug with a long wand and got into pretty much everywhere with just jacking the car up a bit. Up here, you can buy the rustproofing oil in bulk

I never heard of it, but it sounds like it would work. Get a gallon of WD-40 or Marvel Mystery oil and a garden sprayer.

I've heard of the electronic method, but don't know much about it. I'm thinking I'll get it done sometime this summer to stop the rust from continuing - but I'm still wondering "how much is too much". It's still a fairly low mileage car and I'd hate to see the cancer spread before it's way too late. Hopefully, it isn't too late already.
You can take a good look in a couple weeks at Dan-lisle and tell me what you think.

I admit it. I fog the bottom of all of our cars with a fine coat of oil each year. I get about 15 years out of each body with NNY . It really saves your brake lines.
