I've read other threads here on rust proofing, but none - as far as I read - addressed this.

1. While I was being pitched to purchase a $600 6-year Toyota rust prevention package, a process which encapsulates the rustable vitals of a the car, I mentioned that on my last RAV I just did the Krown oil spray. The dealer then said how that was not a great idea as it not only makes a mess of your driveway, but the chemicals used in the oil spray work there way into the air of the cabin and you're breathing that stuff in. Sounds quite possible. Any truth to this? Thoughts?

2. Also.. read numerous articles outside the forum that said, unless your vehicle is brand spanking new with almost zero road time, rust proofing is a waste of money as the oil coating, waxing, Ziebarting, etc is just being laid on top of, and mixing with the dirt, dust and crap that's already there and not doing anything to inhibit rust to a significant degree.... the logic being you wouldn't wax & polish a dirty, dusty, muddy car surface and expect it to shine like a new vehicle, would you? Thoughts?

Disclaimer... I know this is an old hat subject, but I'm a cleanliness OCD guy. Y'up... I'm the guy that keeps waterless spray cleaner, microfiber towels, and spray detailer in my RAV4 so I'll have something to do in the parking lot while the wife is picking up a few groceries. LOL.

I have not heard of any health problems associated with oil sprays. I have been getting oil sprays (Oil Tech and Krown) for over 25 years, and I personally have not suffered any health effects. It's odd that your dealer has heard about the health risk, and yet Krown employees don't seem to wear any serious protective equipment, nor does the government dictate that they use any equipment . The mess in the driveway is only a temporary oil spot that washes away with rainfall after 6-8 weeks. It does not cause permanent damage like a gasoline spill would do. Some of the oil spray companies use very thick oils that they advertise as "dripless". I feel the real benifit of oil is that it creeps to cover the entire surface of the metal. I think a dripless product defeats that benefit of oil.

Rust is the iron in the metal combining with oxygen in the air, creating Iron Oxide (which is reddish brown in color). Oil forms a film on the metal which separates it from the oxygen, and prevents further oxidation. On a dirty underside of a vehicle, the oil soaks into the dust and still contacts the metal underneath the dirt. The dirt itself remains oil soaked and provides an additional layer to prevent abrasion of the metal from the sandblasting effect of driving on the roads.

What do you think will happen when you spray wax and tar based undercoatings on dirt?. The material will dry on the surface of the dirt and then fall off when you hit a bump.

And finally it is never too late to apply an oil spray. Even if rust has already developed, the spray will stop it in it's tracks, and prevent it from getting any worse.

I think/thought the same thing as you on both counts, but so many articles I have read have the opposite opinion, the biggest being that any undercoating is a waste of time because.. well... ah heck.. here:

Ya can't win. You can't change the rules. You can't even leave the game.:wall

The link you provided says that rust treatments are not as popular as they once were, because the improvements in metallurgy and car design are resulting in less damage being caused by rust. The article does not say that spraying a car that is not "brand spanking new" is a waste of time.

I think if you plan on keeping a car for less than 4-5 years, then you may not require a rust treatment because the rust damage would not have perforated the metal and become visible on the exterior painted surfaces. On the other hand if you are going to keep your car longer, then an oil spray will keep the rust from causing visible damage.

My first thought is don't believe anything a car dealer tells you.

I know nothing of oil treatments for rust prevention but Krown has been around since 1986. My thoughts are that you are really over thinking this.

Yeah.. that was a different article. Sorry. So darn many to choose from.

I agree with the dripless being a very thick oil that does not creep. I even got the spray can from Metropolitan and it was the same; it would not ooze/spread.

I have used dripless for 2 years now because I just don't like the oil stain at the bottom of the doors; they spray it inside after making holes in the doors.

This time I will ask them to do regular oil spray everywhere except the doors will get dripless. Best of both worlds.

Metropolitan dripless is also environmentally friendly but it biodegrades within a year I checked my rear hatch panel and it was bone dry!!! May be it would have been different with regular oil spray.

The last time I had a car rustproofed(quite a few years ago)they drilled holes in the rocker panels to spray the stuff in. After a few years, guess where the only rust on the car appeared?.....the holes they drilled in the rockers.

 

[vanib]

That's why it is a yearly treatment and the cap for the holes need to be greased. I did not have issues with my cars with rockers drilled. In my RAV4, I took off the door sill temporarily so they did not have to drill holes in that area.
