Living in a rust belt in Canada, that arguably has some of the worse environments for causing vehicles to rot. I would strongly recommend not covering rust with any black tar/rubber or ashpalt like product. wheel wells, are fine, to help prevent further chipping, You can easily cause a situation where moisture is trapped between the undercoating and metal. This can make a bad situation worse. What we do here is once a year you spray your vehicle with a oil undercoating. Usually the best systems your doors, rocker panels etc are drilled and sprayed with a thin oil and a heavier oil sometimes sticky or even slightly waxy is used on the underneath. This will stop rust dead, if you keep the metal goo'y it won't rust. I have two 30 year old japanse vehicles one of which I daily drive the other is my weekend truck. Both have original paint, they are both a little rough around the edges, but they are about as rusty as when I got them, Nearly a decade ago!

[@rickjames9477]

I would agree a system like the one shown is more for a new vehicle, if rust is present you want to oil spray it, not undercoat it with anything that dries

[@alb12345672]

I agree, someone who sold me my explorer thought they were doing me a favor with a nice black rubber undercoat. A few years later its a rust bucket! I did some prep with rust converter and rustoleum and use fluid film and oil on everything now.

[@edbap2132]

[@jbncnow]

Doesnt oil just attract dust and leaves ect and if you get any on the exhaust it will smell and smoke and if you ever have a major coliision and have to do any welding or cutting or painting in hidden areas well oil and paint dont my too well, i dont know why the car manufacturs cant used better corrsion resistant steel or better coatings or a bedliner epoxy or powder coat the suspension parts.My 86 Chevy trucks chassis is a joke, some of the front suspension wasnt even painted from the factory and the cab floor underside doesnt even have paint on it hardley at all! you can see black primer, same thing under the bed, its more overspray than an attempt at a paint job, the underside of the doors are the same thing just barely any paint at all, i took the entire chassis apart and sand blasted everything then epoxy primed everything then repainted it it with this hammered looking greyish black paint and powdercoated all the suspension parts i could unbolt from the truck .You would think by now on a 30-40,000 dollar vehicle you shouldnt have to do extra steps to keep your new car from dissolving out from under you by now,also it seems like exsess oil would also drip off on your garage floor, i could never live up where you get that kind of winter weather cause it would drive me crazy to have my vehicles so filthy from driving in snow and rod salt all the time. It gets bad enough here in North Carolina where we get about 3 snowfalls a season but then its gone in 3-4 days ,when, you live in Michigan or Canda your dealing with this mess for months, i just couldnt drive a brand new car in that salt and snow and ruin it so fast, my wifes sister from Plymouth Michigan has a 3 year old Honda CRV and wanted me to put brakes on it ,i was shocked at the amount of rust on the heads of bolts of the brake system and on the exhaust clamps and the hangers ect, My brother lives in Orlando Fl and his 21 year old Suburban still has the original factory exhaust system on it at 360,000 miles! that salt is death to any car even if your vigalent, How about using a 5 gallon contailer of WD-40 and putting it in a paint spayer o spray bottle or hudsen spayer?, it is supposed to displace water, im shure you have to protect the disc brakes and anything that gives off heat, and doesnt oil break down rubber bushings and stuff?

[@merkurman]

Leaves and other large debris aren't attracted to the oil, as it gets blown away with the wind. Dust and fine sand are actually your friends. It does get embedded in the oil film and helps prevent it from getting washed away. If you get any bodywork done, the oil is quickly removed with solvents where needed. The products we use up here are friendly to bushings and rubber hoses, as well as plastics. It's also great for electrical connections as it's dielectric and protects against corrosion on the connector terminals and wiring. WD40 isn't very good at long-term protection as it's watery thin and gets washed away quite quickly. It's also a solvent, and will take with it any other oily coating that is protecting the metal, and will cause it to rust faster. I hate WD40. It's not particularly good at doing anything, except temporarily displacing moisture, and I cringe when anyone mentions it being used to lubricate or protect anything. I have a 1988 Merkur Scorpio that's lived through many Northeast winters, and while I've never taken it to get professionally oil sprayed, I have emptied many cans of Krown or Rust Check (the two most popular brands of oil rustproofing spray) inside and under it over the years, and once you scrape off the 1/4" thick layer of caked on slime that coats the underbelly, it's as fresh as a daisy. Every nut and bolt comes off with ease, and all my fuel and brake lines are not only original, but still wear their OE factory paint coatings. The bodywork isn't perfect, but the undersides are about on par with a 3-5 year old vehicle that wasn't oil sprayed. It's a never-ending battle up here, but there are those of us that fight the good fight. And to make up for all the heartache and pain the snow and salt cause us, we take out our aggression in empty parking lots after a fresh dumping of the white stuff. There aren't many things on Earth that can reduce an adult man to a giddy, giggling schoolboy faster than a big snowy parking lot and a RWD car. :)

Damn, going from sleeping in your Impala to being able to drive cars like your own Porsche is incredible. Larry you seem like a legit dude who has clawed your way to the top.

[@takeadayofff]

The proper time to undercoat a car is when it is brand new. It will stick better and is a better long-term investment. Undercoating a unibody vehicle will make it noticeably quieter due to rubberised undercoat absorbing the road noise propagating through the metal. That's exactly how old Benzs and BMs had a quiet ride. 2 coats will give some improvement, but 5-6 is worth the effort.

[@Lincolnator721]

This is exactly why I'd like to buy a new car... people neglect their cars, which is why I don't want to buy someone else's problems... but I did anyway and that's all I can afford for now.

[@markm0000]

Going through a old car from top to bottom with new paint, under coating, insulation, dampeners, etc. is far cheaper than a new car. I plan on returning my old truck to better-than-new condition with a new motor, manual transmission, exhaust, and programmer that can really let me dial in the gas mileage.

[@ogopogoful]

hum...I did about 2-3 coats over my whole car and 4-5 coats on just the cabin area, with about half another on the trunk side(ran out) think I'll notice a large difference?

[@bcubed72]

I'd sooner do an oil undercoating than a rubberized undercoating. The downside is you have to oil the chassis every year or so...the upside is, unlike rubber, it won't "peel away" and create an environment where water and salt can get trapped underneath, actually accelerating the process.

[@andrewchandler5775]

If you have OCD then never do this to your vehicle it will just make the rust worse by sealing it in and corrode underneath without evening you knowing, until your vehicle falls apart one day and you are like OH SHIT WHAT HAPPENED.

That only happens if you put it on too thick. If it gets over 1/8", it will dry and crack, and then trap water.

I have a 50 year old sedan that was undercoated with this type of rubberized coating for most of its life due to it being used in Idaho.

Given the age of the vehicle and the condition of the undercarriage I would have opted NOT to use a rubberized undercoating. I'm all for undercoating, I have my car oil sprayed by Krown each fall and although it makes a mess I know my car is protected because it creeps all winter.

[@righteousred723]

Lmao krown is trash

[@ILovedThe90s1]

I undercoated my Silverado last summer in weekend warrior fashion. My frame rails were just as bad as this Impala - Instead of primer and a rubberized true undercoat I used POR-15 and a paint brush with great results. No brush strokes because it self levels, also after wire brushing I wiped everything down with lacquer thinner to remove the dust.

[@georgigeogiev8999]

@AMMO NYC Can you post a picture of the undercoating after the 2 years , Is it still in good shape ?

[@NihadH]

I bet that the rubberized undercoating is still in great shape. The real question is in which shape is the poor metal behind it! Rubberized undercoatings are notorious for looking pristine while the metal behind them rots like in a grave due to locked in moisture.

[@casheighty8]

LKQ Canada has it now

[@zososldier]

It will still rust. you just want see it happen now. Need to treat rust by removing it completely or neutralizing it with chemicals.

[@dd3vob638]

adam courtney you understand that if you completely cover it off the metal won't oxidize, I don't think you understand how metal rusts...

[@zososldier]

Ok, sure. so all pro body workers just paint right over surface rust and unpreped metal. I get that paint will cover the rust blocking oxidation but you still have the issue of chemicals that oxidize metal and affect paint plus the loose particles will cause flaking which all leads to more corrosion.

[@punkrrrock]

I would assume the primer they applied being named for applying to rusted surfaces would have chemicals in it to neutralize/stop rust.

[@MrGrentch]

Sorry D3VO, that's not how this works. It's already oxidising and will continue to do so. This kinda DIY "easy" over painting will slow the process down alright, which is fine for a car that will be moved on/scrapped in a few years(or if you live in a very dry climate). It is _not_ fine for lets say any car which the owner wants to preserve as a classic for the future. The rust will continue eating away at good steel and now it will be hidden by the undercoat layer while it's doing so. Not good. As for added chemicals to neutralise rust as Punkrrrock mentioned, they are only a solution for _extremely_ thin layers of surface rust as the coatings don't penetrate very far. Flaking rust has gone far beyond that point and any bubbling of the paint surface means that the metal has rusted through and become porous and needs to be cut out. _Proper_ rust treatment: remove all visible traces of rust. Treat remaining steel with rust "neutralising" chemicals. Cover surface with high zinc primer. Apply top coat. I'd personally not put undercoatings on top of that as I prefer to be able to keep an eye on proceedings, so would use the various anti rust wax coatings on the market, but they do need more annual upkeep. Just my humble anyway. .

Hey sir ...GREAT VIDEO. Makes me sad though. I too owned a vehicle with sentimental value..I did everything with her. She was a 92 Taurus. Original engine, One rebuilt tranny. I drove her till last year , when driving from Queens to Long Island (Smith Town)... Head gasket blew, after she arrived to our job destination safely, her head gasket blew. 380,000 miles!!!! I had planned on undercoating her after that winter. Never had that opportunity. I had no choice but to put her down. No funds to fix, no where to store her. After seeing your video, and hearing how much your beautiful Impala meant to you....I started feling bummed, and wished I could have repaired her and kept her. I was trying to reach 400,000+ miles. Anyway..... Great video. Will attempt under coating on the replacement 2003 Matrix I now own. Rust every where. Will be following your guidance. Thank you. Christopher, Queens, Ny.

Yes 100% if your in a dry climate and wanna make the underneath of your car look new again but out here in Canada if we did that 5 years you wouldn’t have a bottom or frame on your car or truck in Canada you gotta use a oil under coating like (fluid film) (known) or (pro-form) and have it drilled.

[@MrZdvy]

Obviously this should have been done BEFORE the car had any rust. The heavely pitted frame rails, floorpans etc. should have been blasted to get clear metal. In my experience the rust will always come back unless you really remove all the rust first. I've been there... I know some products will apply right over (slight) rust but it just doesn't seem right to me. I am curious what you did to prevent rust from the inside-out, which as you know has nothing to do with undercoating. Best regards.

[@harris8390]

+MrZdvy Rustoleum makes a product called rust reformer which basically turns a rusty oxidized surface into a primer surface ready for paint without any sanding needed. I'm surprised Larry didn't use that here. Although I can't say how it holds up in the long run I sprayed it as an undercoating to me lawn mower 4 months ago and its held up strong.

[@ohiodigger4391]

I've heard undercoating your vehicle is not good for it as the finish can crack and will trap moisture. I live in NE Ohio where we loooove putting salt on the roads. I plan on spraying the underside of my '89 Ford F-250 with Fluid Film. Much like spraying with used motor oil but the Fluid Film is biodegradable and won't harm rubber bushings or electrical connections. It's certainly not a one time spray. I plan on spraying twice a year.

Is the garden sprayer able to spray something as thick as motor oil? Is it just the hand pump kind of sprayer? I have a garden sprayer but figured it wouldn't be able to pull the oil up and pump it out.

[@lar4305]

+Ohio Digger Yea, just thin it a little bit with anything like paint thinner or lacquer thinner. It sprays on really well. And the thinner will evaporate and the oil will go back to being thick again. I saturate every hole inside the rails till it runs out.

[@TheOlah]

+lar4305 you can thin it out. But I would recommend getting one of the kits they sell with the gun. You will waste less and apply it more evenly. I also live in NE Ohio and have a GMC Yukon from North Carolina that has hardly any rust. I put it in in October and it is still there. Only place that has really washed off is around the wheel wells and you can easily touch them up. Overall I am satisfied with the durability of it. It does thicken up drastically if left out in the cold so I would recommend bringing it up to room temperate before you spray it.

[@ohiodigger4391]

What part of NE Ohio? I'm in Ytown. I had bought a gun off Amazon with good reviews from people who specifically used it for spraying Fluid Film. I was hoping to have sprayed it by now but never got a chance and now they started dropping salt. So I'll probably leave it sit this winter and spray it in the spring. I was thinking about getting one of those hot plate warmers that you just plug in and setting the Fluid Film can on there to warm it real nice. How often do you have to spray the Yukon? Do you get more than one spray from a gallon of it? It's like $50/gallon. I only put about 2500 miles on the truck this year so maybe I could get away with one spray a year but we will see. I'd rather buy more Fluid Film than have rust repair done I guess.

[@richalvarado6890]

This has got to be the best tool I have seen in quite a long time. I will be adding this to my arsenal of tools and use it as an up-sell to my customers. I wonder if it can handle regular auto paint for those ultra-finicky clients.

[@DovahDoVolom]

@@napoleon23232 Lot of rubber based undercoating can trap water against the metal encouraging rust that the user would never notice and it would slowly get worse over time.

[@sub_second_life3174]

Dovah Do Volom this is why the prep work is so important. You do this on a summer day and you pressure wash the entire bottom, scrape off any built up rust, dry with compressed air and maybe let sit for a day or two, dry again and then undercoat. If there’s no moisture to trap then you will prevent future rust or slow and maybe stop the current accumulation of wear. You don’t undercoat 15 minutes after you wash it lol

[@USAlien234]

@@sub_second_life3174 its still locking any moisture that is in there in. Salty water from all the salt used in NY during the winter month's seeps into everything by natural chemical reaction. ANY small cracks or "oops I missed a spot" and that salt water is gonna eat the metal alive. It has no place to go, its trapped. Worst of all you'll never see it and think everything is okay. There are other products out there I would suggest. One being Fluid Film. You could probably use the blower in this video to do the work for you as well. If anything, before you decide, do a search on here for the dangers of rubber based under coatings and see what alternatives there are. You may be suprised by what you find. Just my 2 cents. Well... that was more like a quarter but hey, you probably didnt read this far anyway -✌😆

[@Charkatak]

Good video! Recently I went to wheel repair shop and guy used regular floor jack under the jacking points which is fine. I usually put something on top of the jack so it won't remove the factory layer from these spots and to eliminate corrosion/rust. It was just few days ago, so there is no rust of any kind, but I do see points where protective layer chipped off in couple of spots. Would you recommend to clean the area and spray Rust-Oleum Undercoating or Rust-Oleum Automotive Rust Reformer? Just want the surface to be protected.

undercoating destroys your car.....ask ANY NY state mechanic. moisture still gets in....but is not able to dry

[@calebniederhofer6529]

You are absolutely correct, most people just really don't understand all this does is destroy the car. You won't ever get all of it off either, It not only traps moister, But If any salt ever gets in it spreads like wildfire even further.

Overall I like this video with one exception: doesn't coating the driveshaft cause it to be out of balance? I thought you coated the driveshaft.

[@TomGavin1]

Then wouldn't the logic hold that when the drive shaft rusted and metal flakes fell off, the drive shaft would then 'be out of balance'

[@unit3edkarnage]

Tom Gavin undercoating is way thicker than paint it will add vibration don't spray your driveshaft

[@RolandAshcroft]

It's easier to get a company to do this for you, for about a few hundred bucks. Instead of buying the tool and materials for a lot more, just to do this once per decade .

[@alycestapleton]

RolandAshcroft seems like your lazy or a clueless fuckwit that can’t change a tyre also I’ve done is many times and it’s easy as fuck but best results remove the whole suspension,fuel tank and other things that are in the way

[@IMWEZL2]

Gaz Girl I agree on taking the time to drop the exhaust. I would probably cover the suspension and brakes just to maintain alignment specs. I would probably cover any bushings as well just to be on the safe side in case any of the products deteriorate the bushing material.

[@livefreeordie4850]

Great idea

[@aka1boi]

If you want something done right do it yourself. Companies just want your "few hundred bucks." They do not prep your vehicle. Instead they mask over the rust rather than neutralize. The finished product looks the same and you'll be none the wiser.

[@livefreeordie4850]

Very true. I had my car painted at Maaco & they never even primmered the vehicle & the paint was falling off like bread crumbs barely after a year. It looked fantastic initially.

This is a terrible recommendation. It degrades any plastics/rubbers on the outside/underside of your car, not to mention you're spreading motor oil all over the place while you drive when it rains/etc.

[@lar4305]

Used engine oil is what i use once a year on all my cars. They don't rust. spray everything under the car, inside rockers and door bottoms.

[@livefreeordie4850]

What would you recommend for covering the interior wheel wells that are already covered by Rattle Trap sound deadener? I need something durable that can tolerate a bit of abuse? I thought about Rustoleum bedliner but not sure it will stick properly to the sound deadener. Also not sure it is safe for interior use. I would like it to be very simple, but can be outside the box.

[@waynebinky]

This method as many have pointed out only hides the rust and doesn't stop it's progression. Even the insides of the frame get zero protection from this and that's how most frames and channels rot out. Just picked up a new RAV4 and applied Fluid Film to it. I used rubberized coatings in the past on a rusty vehicle and a couple years later it was lifting from the rust action below. I'll stick with my Fluid Film. Get it? Stick?

[@frankbaran3800]

Don’t ever undercoat a vehicle ! Ask any professional any mechanic.

[@calebniederhofer6529]

You are 100% correct, it essentially destroys the car, and you sill never get it all off . Not only that if salt gets in , it spreads like wildfire with the moisture.

[@vladmircea3174]

Idk about you, but all the cars in europe have factory rubberized undercoating. I would like you to try on a piece a sheet metal and let it outdoors to see whats happening. So first make sure the metal is as clean as possible from any rust, stains and oils. Then, scrub everything with fine sandpaper for better grip. After this, apply primer and sand it too after its dry, and eventually, apply the rubberized undercoating 2 times. You will never need to undercoat your car ever again, and it will not cause rust! All its needed its some of your time, attention to details and working clean

[@Carnius797]

It’s mind boggling that you’re encouraging people to do this.

[@Totemparadox]

How so?

[@Carnius797]

Terrible thing to do look into it. The moisture gets trapped and makes vehicles rust out even quicker. Also a lot of important components get coated over making them even harder to work on. Look up Eric the car guy under costing vehicle. Truck with 55k miles completely trashed because of this stuff. Don’t do it.

The primer coat is designed to turn the flaky rust into a much stronger form of iron oxide that's inert and bonds well with paint.

[@Ma77riK]

thanks for showing the entire world that you dont know jack shit about.....well what we consider pretty basic shit actually, even a basic primer sealer will stop rust, because your blocking its source of oxygen it needs to oxidize. so yes hes covering the rust, and killing it.
