Rubberized Undercoating Will Destroy Your Car!

[@SouthMainAuto]

I try to speak really clear and slow in the video however that does not seem to be to effective so I will write it out here as slow as I can type so you can follow along: A: This was not a DIY at home job after the truck was already rusted. This truck was sprayed by Ziebart here in NY the day it was purchased NEW before the customer took delivery of the vehicle. I have the receipts to prove it. B: Every year after the original date of purchase it was taking in to Ziebart to have the coating "reapplied" per their recommendation to "keep the warranty." C: This shit will destroy your car no matter how much "surface prep" you do. I have been working in the salt belt as a mechanic for over 25 years. This stuff that Ziebart sprays on is complete shit and will 100% destroy your vehicle at an accelerated rate. D: Use Fluid Film, Krown, NOHC, surface shield or some other for of "oil undercoating" if you live in the rust belt and want your car to last more than 11 years E: You have a nice day 👍🏼

The bigger reason that GM and Chrysler have major corrosion issues is due to reduced costs in metal plating processes at the factory. Nothing is cadmium played anymore and hex chrome has been eliminated on anything 2010 and newer due to environmental and cost. Same problem in the aerospace industry. New Cessna 172’s have major corrosion issues in the tail section after just a few years. Yet a chromated tail section from a 1955 Cessna 172 still looks brand new today. Build it cheap....build it fast....sell it at a high price....shorter service life. My 2007 Lexus chassis (all hex chrome and cad plated parts) has minimal rust and I live in the Midwest where we have nuclear road salt. This year I will give fluid film a try.

Cases like this are literally the reason why the civil judicial system exists. If you bought a product from a store, that claimed to meet or exceed all US regulations, you brought that product home, and it did not work, would you not try and return it? What if the store told you "tough shit"? What if they had a sign outside that outlined their return policy, which was conveniently missing when you returned? What if instead of simply not working, the product had an adverse affect on your health? Your safety? Are you telling me you'd lie down and take it? If the product caused your home to burn to the ground, would you be satisfied with a simple refund? Would you not even try to recoup the value of your destroyed property? The simple fact is, this person purchased a product that not only did not work as advertised, but also caused damage to this person's property, to which the product was applied.

In cold seasons (after application) it doesn`t harden like rubberrized coat or mastic and remains on the metal surface without the formation of air bags for moisture. In first hot season after application it could have been dripping from under the car for week or two.

This is actually extremely common in the rust belt. It’s very sad. I live in Vermont, close to upstate ny. The rust is just as bad.

My 2013 Chevy frame looks like it’s been submerged in the ocean. Rust and flaking paint front to back on the frame. Body is okay though... for now. I suspect I’ll still be making payments on it when the body starts to rust out. And when it’s paid off I’ll be left with a pile of junk I can’t sell for a couple grand. I see trucks on a daily basis that are 2009 or 2010 model year that are so rusty they’ll see the crusher by this time next year. My 09 ford had about had it before I bought my Chevy. The cab corners were pretty bad and the rockers were totally gone. Next truck will be likely be some 90’s-2000’s cheap thing from down south.

[@jeffarcher400]

I've battled rust on old cars and saltwater boats and trailers. The rust converter products that turn the metal black actually change the metal and lock out oxidation. If the rust is deep it will bubble up again. Chipping away the surface before treatment helps. In a very good KZbin video there's a test and POR product won decisively. I've just started that one a year ago and it is doing good. Forms a hard black paint able surface. Farm lab is the site or something. They mostly use a zinc phosphate reaction and will turn skin purple. Use gloves. After several coats I use a marine grade zinc primer and marine paint for the sea and cheaper Rust-Oleum for the land. Make sure you don't have slow electric leaks as that can increase rust tenfold. Clean channels along trunk weatherstrip so water flows. Same with drain holes. Check it yearly because rust never sleeps.

For record my brother in law had a 1969 pontiac grand prix. It was so clean . He decided to rubber undercoat frame trying to save any corrosion over time.

The appraiser is partly right. But very little would it cause to devalue a car once you see that it is not hiding patch work beyond its original parts. Just need to look a little closer is all. Sounds to be like this guy was too lazy to give it a few more minutes of looking. It doesn't mean all cars are now devalued with undercoating's on them. And probably not even this one was substantially devalued enough to cause worry or loss. Don't believe anyone you listen to and for God sake don't post something just because now you believe what was being said!

May lead to serious injury or death. It's okay though because it'll probably hold together for a few years usually.

I never use the undercoat, but have used the rubber spray on stone guard, but only in two places. First, on any "tuck under" at the bottom of the car where stones hit. Just keep an eye on it, being prepared to repair as nevessary. The other is a bit more unusual, but very effective on old cars. Using chalk dust i outline all the chrome trim, then carefully remove the trim. I mask off around the trim area, then sorsy on the rubber stone guard. Allow it to dry then prime and paint. Reinstall the trim, and nobody can tell. The rubber forms a barrier between car and trim as well as civering the sides of any holes for trim clips. The barrier works because it prevents a galvanic reaction between dissimilar metals. I've seen this last more than 20 years with zero rust under the trim.

[@puckcat22679]

Any undercoating needs to be breathable. Meaning that it will allow any moisture that gets in to get out. Oil based coatings are good, though a disaster to the environment, as are wax based coatings. I personally prefer the wax, as you can see through it (and therefore see potential problems) and they're thin enough that they won't plug drain holes, but they don't like really high temperatures, so if you steam clean the underside of your car, you'll need to recoat anywhere it melted off. Still, Volvo switched to the wax in 1992, and the later cars simply don't rust out unless you're really stupid. As for that truck, the frames on GM trucks are made of weathering steel. They're SUPPOSED to develop a light coating of rust as the factory spray coat wears off. That light coating protects the rest of it- as long as it can breathe. Apply that crap to it, and all bets are off.

[@MortalOnlineJourney]

What you are describing in this video is the result of a failed application of rubberized undercoating. I have been installing and correcting corrosion protection jobs for about 20 years. If the vehicle is already starting to experience corrosion (Even a couple days of salty driving will do it) and these products are applied without proper prep, it will result in the condition you cover in this video. These products need to be applied to clean metal on all the easily accesible surfaces on the undercarriage. Then, all the cavities such as the rockers, frame, bedsides, subframes, door skins etc need to be treated with a more fluid protection product such as fluid film or other similar products. During a professional installation, all connections that could cause mechanics problems like you describe SHOULD BE taped off. I've been in probably 100+ shops and maybe 5 of them installed these products correctly. It's a major scam and people are being ripped off because a barrel of product is at most $1000. One barrel will do 30-50 vehicles. Customers are paying almost the cost of the whole barrel for one application. These poor no prep jobs that result in horrible rust only take 30 minutes to do. Properly prepped and applied you're looking at about half a day on a 3/4 ton truck. So installers are not taking the time and ripping everyone off for quick profits, taking advantage of customers lack of knowledge. Properly applied, rubberized undercoating offers amazing benefits. But the only way to keep your vehicle completely free of terrible corrosion is to not drive in salt. Buy an older beater for the winter, you are actually saving your money on depreciation of newer vehicles if you do decide to go that route.

[@buffalostate1]

i agree. More prep . Defiantly was dirty or had moisture/salt on it before spraying.m i have a 2015 chevy and the stock frame coating is like tar. I heard u dont want to spray fluid film on it . they say it will eat it away?

[@naegleriafowleri76]

I was thinking of doing this to my 2014 car, which has some rust spots on the control arms, but not anymore. Is there anything that can be done? Applied on top of it that would not cause this disaster? What about using a rust converter, encapsulator, they usually come in black

[@biohazardlnfS]

He said moisture gets stuck between the frame and the coating so sounds like it's not dry or eve. Small amounts cause massive rust out

[@silverify]

without any kind of protection, the car will last at least 20 years. How do you describe that.. If this ruins in a quicker time

[@moodberry]

I don't believe that there is a "proper" way to install a coating. It's the edges of ANY coating that will allow seepage of salt and water between it and the frame. Even if the coating is bonded to the metal, the edges will still allow seepage. Then, it's bye-bye frame. If I lived in the NE, I would consider a physical barrier between the frame and road, like they put underneath RVs. A plastic barrier that would prevent the salt from getting int here to begin with. Then, after the winter, remove it, wash the frame with fresh water until the next winter.

Due to watching this video I have been Krowning my new 2023 Tacoma ever since day one before its first winter. Thank man.

[@MotownVideo]

20 years ago I had a Lincoln with air suspension that had Ziebart treatment. After two years trying to fix the air suspension, I gave up and sold it. The buyer thought he could easily fix it. I wished him luck and found out six months later he even gave up!

[@nowthatsfunny1]

Por 15 to me is the best rust protection. It's fluid going on and seals as hard as power coating. I rhinolined the bottom of my truck and it did the same thing as your video...rotted through. I thin applied POR 15 AND THAT Stuff is amazing. Don't get it on you cause it's like a tattoo. It won't come off

[@co8539]

Good to hear brother. I just bought some for my lightly rusted underside. Excited to use it

[@anthonyevans4000]

Outstanding video Sir. People heed the warning. Never use any spray on undercoating. I use fluid film inside my rockers/doors/fenders. I use LPS 3 on frame/undercarriage/brake lines. My 2010 looks factory fresh living up in Vermont.

[@willhall640]

It's all about the prep before application. We do undercoatings and offer a 5 and 10 year warranty for cars that are inspected annually. All surfaces must be completely cleaned, treated and completely dried before application. I've have a 1973 and a 1974 VW Thing that was treated several years ago and there is no sign of failure on either. Not one bubble. The moisture that was between the coating and the metal on this truck was there before the coating was applied.

I’ve always used boiled linseed oil annually on my ‘99 Jeep TJ with 300k miles. I live in an area where roads are salted. I’ve had amazing results with this simple product and there isn’t any serious rust on the body or frame and it’s cheap.

[@dieselman8v923]

We used to spray diesel fuel on our old sprayer trucks. It was not a clean method and it collected dirt but when you washed it off the frames looked brand new paint and all. Lots of good methods out there for sure.

[@Micko350]

@@dieselman8v923 we used to spray diesel all over our race cars so the mud would just fall of mostly & when you 'hit' it with the Gerni it dropped right off!

[@highlypolishedturd7947]

Damn! I don't blame you for refusing to work on cars with this crap on it, but I'm glad you did this one on video. I've never trusted the thick and goopy sort of undercoating, but it's worse than I thought. I'm in a very salty area too, and get an oil spray every year. In my Young And Foolish years, I worked at a couple of car dealers, prepping new cars to go out when sold. The sales staff always pushed their "rust proofing", which was a thick goopy crap like Ziebart. The first time I saw it, I figured that had to be trouble.

[@darkwaterartsdesigns9269]

I cant thank you enough for posting this video. My husband had our jeep wrangler scheduled for this. I cancelled it immediately!

[@erichimes3062]

He is correct-I switched to fluid film early on thankfully on my Cherokee, and it seems to be working pretty well. Also: apply liberally on metal under battery tray to resist acid-induced corrosion

[@E80-t6e]

Fluid film is good stuff!

I have been saying this for years. ANY rubber based product needs to stay away from the underside of any vehicle at all costs. The only rust prevention stuff that works is oil based, krown, fluid film, etc.

[@wally1957]

When I ordered a new truck i had the dealer perform a undercoating prior to delivery. Undercoating should only be applied before any rust is present.

[@scavenom2008]

Unfortunately even cars from the dealer are rusted already. I don't understand this half ass behavior. Why wouldn't they paint everything? Sometimes they leave the axles, hubs and drive shafts unpainted

We used to pressure wash the undercarriage to clean off the dirt, let it dry, then spray them with chainsaw lubricant, which is a lot cheaper than Fluid Film. Worked pretty well from what I remember. I still have my 1984 Chevy, and it has no more rust than a 2006 GMC I bought used last year. The winner, though, is the 2007 Honda Pilot.

[@tompeter7326]

in Germany we have plenty of salt in winter times on the road. Black "Bitumen" undercoating was popular for many years with same results as you show. I preferred the wax type undercoating therefor. Well refurbishing this frame will cost a fortune I guess, maybe with an ultra strong water sandblasting it could be achieved ...

[@tirdkat6104]

Yeah, sounds like you're describing products like Wool Wax or Fluid Film (Not sure if those brands are sold there). That's the only way to do it. Spray it on every fall before winter if you're in a high-salt area, or every 2 years if it doesn't see as much salt.
