Undercoating Protection Option ?

Please excuse if this is a totally laughable question -
but I really need to ask it -

Somewhere some time back, on one of these jeep forums - may have been the Wrangler one - I read someone's complaint that they did not choose the undercoating option when they bought their jeep, and now they totally regret it as the underside is completely rusting. Not only were they complaining about the rust, but also about having to pay for the undercoating option as they felt strongly that it should just come standard on all jeeps.

We are getting all set to order a 2010 Jeep Liberty Limited, and when I go on the Jeep build it site, there is no mention of an undercoating option - nor can I find any info. about undercoating on the jeep site.

I am not even sure if it really is an option, but I just want to be knowledgable if/when the option is presented to us at ordering time.

Do I want it ? Why or why not ? (I have heard of people laughing at people who buy it...)
Or, best of all, does anyone know if the underside of the Liberty comes standard with undercoating protection ?

As always, thanks! for any and all input.
This forum is the best...

I have never heard of this being offered as an option before.

This is normally a "dealer offered" service if they have the facilities, otherwise they farm it out. You can find other shops that do it by Automotive undercoatings or you can do it yourself. If you do it yourself find a quick drying brand; the only ones that I've used I got at NAPA in both spray and brush on (many years ago) and they worked great.

All automotive body panels have had a zinc or zinc-phosphate coating on them since the late '80's/early '90's and most automotive paints also contain those chemicals as a rust preventative. That's why you don't see as many "rust buckets" as you used to, however this does not apply to the brackets and other components you'll find on the undercarriage, just the sheet metal.

This would be a project that you could do yourself and keep a lot of $'s in your own pocket.

Should you do it? Well, the standard corrosion testing is done with a salt spay so if you live near either coast or where they use salt on the roads during the winter I would say yes. Also, it's something you can do later on as long as the undercarriage is clean. Steam cleaned if necessary.

I have used Ziebart rust proofing on my Jeeps. They do a good job. If you are going to have it applied you may also want inquire about their sound deadening . The additional cost is well worth it. About $50 extra (maybe that was a deal I don't know). They want you to return every year to have it inspected and touched up to keep the warranty in place but I never did (at additional cost).
