Re: undercoating your jeep

Rhino Line the underneath and be done with it.

But to do it right would cost atleast $1000 or more

I used this product Fluid FilmŪ | Corrosion Preventative, Lubricant and Rust Inhibitor

The more liquid is sprayed into the doors, frames etc the sticky ones is brushed on. We used within the Navy and my experience is from there it works very well. I used Waxoil before and that was great too, the FluidFilm is just a touch better and offers the different liquidity (is that the right term).

I fully agree that most of the dealers don't have a clue bout this, but there are several shops/chains especially in the rust belt who are pretty good and knowledgeable. They are specialized to this treatment though.

For factory rustproofing, Mercedes is replacing or repainting doors on one model for the manufacturing years 2007-2010 because of rust spots on the lower end.
I believe you were describing Viscosity

Re: undercoating your jeep

i called up the place in long island and they said for the job its 450. but got no idea what they'll be doing to it. after reading up on you guys saying about the drainage holes, i think i might just buy a couple of cans and just spray it down myself before every winter. if not i'll just wash the car weekly or something. the thought of the chances of rusting from the inside out is just ... don't wanna think about that.

Vehicle Undercoating (Nassau & Suffolk County) - COACH AUTO BODY REPAIRS - Syosset, Long Island, NY this is the site for that shop. said its a full day of work doing it and supposed to last forever. but i'm a little iffy on the forever part

Re: undercoating your jeep

Consider how long you plan on owning the vehicle. If you plan on owning it 10 years and the shop will spray it for $1000, then that's a $100 /year investment. You don't have to change oil in your vehicle either, but sooner or later that will catch up with you
also if you neglect it. I spray the underside of my vehicles every summer. It not so much how much does it help as it is that it doesn't hurt. It's part of maintaining the vehicle. Some owners do a good job and some people don't put a dime in their vehicle in the form of preventive maintenance.

Re: undercoating your jeep

Paint all my cars with Eastwoods rust encapsulator paint, brushable seam seal, top coat with chasis black epoxy paint ,then spray bomb with their heavy duty antirust coating. lastly use fluid with wand to flood all inner doors, hatch, rockers, subframes, rear wheel wells.

Re: undercoating your jeep

I've got a lot of fluid film on hand, but I haven't figured out a good way to apply it evenly to the underbody without access to a lift.

I may have to bite the bullet and get a compressor and the 360 degree nozzle, my undercarriage is full of rust already after a year (chicago).

Re: undercoating your jeep

Since this is an old thread, "brought back to life', and I'm a relatively new member here, I'll add my $0.02 worth.....


As somebody mentioned, "rustproofing is so 1980s". Yes, because many people lease their cars, these days, so as long as the car last 4 years, that's all they're concerned about. Leasing took off in the 80s.....


I used to rustproof cars, for "pocket money" back in the 80s-90s. For inside the doors, tailgates, inside the hood and front fenders, I used (and still do) a product called 'LPS 3'. It's a somewhat thick liquid, that coats the metal, but doesn't harden. Good stuff.

so question is, is it worth getting the undercoat done? did some reading an apparently our of the factory theres supposed to be some good coating already so i shouldnt haven't do it. also read the con's for doing it and that it can actually promote more rust forming and what not.
Don't do it, please. That crap does more harm than good.

Best way to keep your Jeep from rusting is to keep it clean. After my last ski trip to Whiteface NY I got home, raised the vehicle high on it's air suspension and rolled underneath it, armed with rain gear and a garden hose. I rinsed out about a cubic yard of New York State.

I believe 60 minutes or some show like that did a story on it years ago. They used to drill small holes to rustproof from the inside. It turned out the cars with the rustproofing rusted much earlier than those without because of the holes that were drilled.
This ^^^^^^^^^^^^^^.

I lived and grew up in Chicago, where roads were salted constantly all Winter long. "Undercoating", "Ziebart", "Rusty Jones", along with "Polyglycoat" were all dealer applied snake oil treatments that were supposed to protect your car. It all made no difference what so ever. In fact many of these type of "rust proofing" treatments made matters worse by trapping salt water in areas that would have drained had they not sprayed that crap everywhere, clogging up drain holes in the process.

Today's automobile manufactures use far more rust resistant materials in car construction that they did when all this type of crap was being sold by everyone and their brother. There is no way around the fact that if you live in the rust belt of the Midwest, and deal with road salt, your car will not last a fraction as long as if you live where road salt is not used. I live in the Phoenix Metro area. I purchased my new Jeep last April, and I have yet to get the tires wet. Except for the 2 times I've washed it since I bought it. In that type of weather, there is no treatment that will allow for a rust belt car to last anywhere near as long. Regardless of what you do to it, or apply on it.

Re: undercoating your jeep

Another thing you have to be careful of in corrosive Winter climates, are these "quarter car washes". Many of them use reclaimed, filtered water. Several years back I had one by me that was enclosed in the freezing weather. Allowing you to pull in, wash off the road salt. Do a quick wipe dry, and leave. I tasted the "rinse water" once, and it has so much dissolved road salt in it, that it was saltier than the ocean!

I agree with the highlighted areas of your post. HOWEVER, going back to something I posted earlier, I use, and will continue to use, LPS3 to "rust proof" my vehicles. I rust proofed the 2005 GMC Canyon, that I traded in on my 2015 Grand Cherokee. Driven through 10 winters, and washed whenever possible, the GMC still looked really good at the time of the trade.

I replaced the speakers in my GC last month, and while I had the door panels off, to install the new speakers, I sprayed the inside of the doors with the LPS3. Having the speakers out, allowed for access to the inside of the doors. There are also "pop-out panels" that give you even more access. Yes, I was careful not to plug the drain holes, and I'm sure that my GC will still look good in 2015.....
