I live in Maine, where the roads are heavily salted in winter, and dealers all push undercoating packages hard on new cars. I didn't have it done because I haven't seen that they're very effective at all in the areas that tend to rust out first (tops of fenders, rocker panels). I have seen them keep brake lines preserved for a long time, but those also tend to last quite a while before rusting out anyhow.

I haven't spent too much time under the iA yet, but it seems to be pretty well covered by plastic or metal sheathing.

So has anyone had theirs undercoated? If so I'd be interested to hear why, and pictures of it would be extra cool.

Some companies drill holes and spray some liquid inside panels, so that might be what helps to prevent some rockers from rusting, which is part of a full rust proofing service.

See this:

And this, with a GOOD point on not drilling holes, instead using existing holes:

I am curious about this too. Part of me feels that the company must put adequate protection on if they are selling it in the north, but then again I don't want damage to my car if it does need extra protection.

I wouldn't mind spending the money for extra protection if I could find a definitive study or proof that it actually works. For this car I think I'm going to skip it and just be diligent about keeping it clean in the winter.

How does this damage a vehicle?

I think he just means he wouldn't want to see the car prematurely rust if it could be prevented.

Yea I meant the salt damaging the car.

Fortunately with salt on a new car you have time to act, unless its a situation where theres exposed metal somewhere due to damage from something... then you're out of luck.

Isn't there some sort of rust proofing oil that can be sprayed onto the underside of your car?
Also wash your car diligently. I usually do it once every one to two weeks depending on the road.

There is, you can buy them in large rattle cans, but I think it can get messy.

I think it's better to just take it to the pro's and have them do it.

Not the dealership but your trusted garage guy. I usually have them spray the underside of my cars and they even do it to the gas door to make sure that doesn't rust either.

Ultimately going to shops that do this a lot will be where most folks will want to go.

Does your shop spray inside the rockers and inside other vital areas?
