This will just make this rust more but hidden behind the rubberized coating. Being from the rust belt, this is fairly common knowledge that you don't put rubberized undercoating over existing rust unless EVERY SINGLE BIT of rust is removed. Need to use a non hardening (usually oil or waxed based) coating

[@El_Diablo_LI]

@Heffalompen That's the problem. It's almost impossible to remove ALL of the rust. Which means what ever you don't remove will be susceptible to worse rusting. This is why non hardening products like Surface Shield, works best for applications like this.

[@roberthayes6329]

Here in rusty Michigan we use Only Fluid Film. Rubber undercoat will only make it look good. Unless you sandblast the frame you will never get all the rust off, but by then powder coat or some other way better process is just better. Just search southmain auto Fluid Film...

What was done to mitigate the rust inside the frame? If you see rust on the outside, there is likely an equivalent amount on the inside. I do think your treatment will slow the rusting process, but it will eventually rust from the inside out unless that is addressed. Did you use a borescope to check the interior of the frame?

I would not spray that inside a shop... getting overspray from the pressure washer everywhere... just take it to a carwash with an undercarriage spray... the rest can be dealt with after a short drive to dry it off wire wheels, and wire brushes... and always use a rust reformer, or rust converter then paint.. never use rubberized undercoatings... they create a pocket for moisture to remain in contact with the frame, and causes more issues. use something annually like woolwax, or fluid film...the oily waxy type stays semi fluid.. so eventually it wears off, but provides protection from rust by not allowing oxidation to occur. air, and moisture cannot get to the metal underneath..

[@48Ballen]

There are about 1000 KZbin videos about jeeps and how the frame rots from the inside out. Unless you coated the inside of the frame with a liquid penetrant this entire activity is just for looks and will not protect the frame at all. It looks great, too bad it will rot in short order.

After all my research that rubberized coating will not protect your frame in time moisture will get under it and trap it in under the coat. What I have done is remove surface rust the clean and prep it with degreaser the apply Por-15 which binds to rust and makes it a paintable surface. And then apply fluid film to the inside of the frame to protect from the frame rusting from inside out.....

[@jampakunchog]

How long does it last before it has to be re applied?

[@2strokemigz]

Let me give everyone some great advice that you don’t have to listen to but i can vouch for…. Get yourself a a wire wheel scrape off all the scale… then get yourself some corroseal rust converter,apply it to the rusty areas it will turn black, NEXT get yourself some Woolwax from amazon and the kelsport spray gun, spray the whole vehicle… the woolwax is oily and will seep into the pores of the metal and actually protect it from rust….. I tried the product used in the video on an old mustang gt of mine here in NJ and this crap made more rust grow… that rust oleum stuff gets one chip from road debris and you’ve opened a whole in the coating to allow moisture in and continue to rust your vehicle from the inside out…. Woolwax or fluid film creates a greasy wax layer that always keeps your frame and body soaked in the oil…. In the military we used cosmoline and oils to store weapons long term… not rubberized costings…. If rubberized coatings were better don’t you think the military would use it to store weapons not in use long term?? I will never use rubberized undercoatings again. I sprayed my f350 with multiple coats of Woolwax 3 years ago and has been through 3 winters in NJ and not a spot of rust anywhere and I know the rust isn’t hiding under a paint like the stuff used in this video

[@stewoe7157]

@@valdius85 The rubberized undercoating traps moisture and rust. No matter how well you try to remove rust, there will always be little nicks in the nooks and cranny's you can't get to. When you spray rubberized coating over those spots, they trap moisture and are never allowed to dry. It's like a greenhouse for rust. So it rusts faster than normal, and worse, you don't see it because it's hidden by the black shiny undercoating. So your frame might be almost rotten trough, without being able to see it. The only time rubberized undercoating could be used successfully is on a brand brand new car that just rolled from the factory with the guarantee there is no rust in there, but I think the best thing is just to stay away from this stuff. Use a paint that reacts with rust and converts it, like the european Hammerite from AzkoNobel. Or lanolin based coatings, like fluid film.

Wait a few months you will be horrified

[@tpelton]

aren't the rubberized coatings generally regarded as the worst undercoating you can use ? they crack and peel, and allow water to collect _under_ the coating hiding and accelerating rust ?

[@imnota]

A good quality undercoating won't crack and peel. Now the big issue with them is you gotta get rid of 100% of the rust before using them, even if you got rid of 99%, that 1% is gonna spread under the undercoating and that's gonna be bad. This is why IMO rubberized undercoating is a thing that should be used after a repair or restoration where you know you got 100% clean metal but for maintenance purposes or improving the longevity of a used car it's just not the right product and some kind of waxy coating is more appropriate. It's all about using the right product in the right application, rather than one product being bad and the other being good. On my e36 restoration what I do is get it all to fully clean bare metal, then use rust converter in the parts that were rusty prior to grinding in order to be sure there's no trace left (even tho it was ground back to clean metal, it gives me peace of mind and cannot hurt), I then use epoxy primer because IMO it's important to seal the metal from the undercoating itself (all factory applications are this way, don't listen to the bullshit said by people or on the can, car manufacturers know better, if you scuff the surface the bond will be good) and only then I use the undercoating. I would never apply it onto a surface that I'm not confident I removed all the rust, and would never apply it on bare metal either. Done properly it provides a chipping protection that no other product can provide.

It's been 5 years now with no new rust. Did my wife's 04 trailblazer 10 years ago with Eastwood's internal frame coating (4 coats). Did the outside of the frame with Rust-Oleum rust reformer and three coats of rustoleum rusty metal primer over the top of that with three coats of rustoleum professional black paint.

A lot of work to coat the outside of the frame when significant rot is usually formed inside the frame. Was the inside frame coated with an oil based fluid?

[@Dawt_Calm]

A Harbor freight 20oz pneumatic spray gun. $20 (need a compressor) 4 foot long flexible tube with a a dispersing tip. $5 for tubing. (I made a tip from scrap plastic) Bar and chain oil. $10 gallon. (bar and chain oil works well because it has an agent in it that causes it to be stickier than regular oil. I actually spray the outer frame with it too) Step 1. Attach flexible tubing to spray gun, attach the dispersal tip to tubing. Step 2. Put tubing down any open hole in the frame, spray and twist as you extract it. Step 3. Profit. I found a plastic cap that fit onto the end of the tubing I melted tiny pin holes in the sides of the cap so it sprays out sideways. Then attached the cap to the hose by crimping with a low profile clamp. A normal hose clamp can bee too large for some holes. I think they actually sell tubes with dispersal caps too. It was cheap to fabricate though. But I also figured out later you can just cap the tube and melt some pin holes in the last couple of inches of tubing too. Very small holes to atomize whatever you decide to spray. (You need that cap on secure or it'll pop off in under high PSI) I only use that spray gun and tubing for that purpose. Have sprayed three vehicles and a trailer every three years for nine years so far. Still have more than half a gallon of bar and chain oil left. It smells and drips a little, not a strong smell but detectable for a few days. And if you want nearly zero drips in your driveway maybe use some thin coat spray instead. Maybe that's a product already, dunno. A disposable can of thin film spray with a 3' or 4' hose on it. Haven't seen it. Would there be a market for that? How many people actually think about the inside of the vehicle's frame. But you're absolutely right, water sits in there over extended periods.

Has the customer given any update on how thd frame is doing since it has been applied

[@48Ballen]

It rotted because they forgot to use a penetrant oil based product on the inside of the frame. All these frames rot from the inside out and there is no protection!!!

[@JTADVENTURE2]

@@48Ballen yeah i have to get my truck sprayed soon. Il make sure of that thanks for the info

[@JohnDoe-ud2cc]

Does it have a oily or waxy feel? Will dirt and mud clean off of it easy? Every other undercoating I have used, dirt sticks to and turns brown.

[@janw.866]

How is it possible to get so much rust in such a short periode of time? I live in the Netherlands and salt is used a lot in the winter, but my 2001 Volvo does not rust at all. Is Jeep delivering cars without a proper anti rust treatment or is it just bad metal that is used?

[@axios76]

How is it holding one year later? Is the rust getting back? What would you say to those who say that rubberized paints trap water underneath? Thanks!

[@thomassankara2857]

I applied a rubberized cost under my tundra and it's very smoky when I start the vehicle? Is there anything I did wrong?

[@SpirosAutomotive]

That's normal. Overspray on the exhaust just needs to burn off.

[@chrisclapp3182]

That looks amazing

[@ItchyKneeSon]

Do you have an update on this now? I know that paint and/or coatings can chip, trap moisture, and end up hiding rust.

[@harleydavidsonroadking9648]

How many can did you need to undercoat that jeep ?

[@louisbelanger8792]

About 8 cans

[@keemgt9699]

you need to put safety goggless, when using that rust scraper men. thats not safe

[@ejaokay]

You forgot to prep the surface following the wore wheel, you need to clean it again with either soapy water or alcohol or that paint will flake off in the future

[@hartman4922]

Took my 2018 JKU with 4000 mi on it to Ziebart for undercoating. First trip I checked underneath to find miss spots. Took it back to inform them and their response was to take it back in for a respray, nice. I checked underneath after the respray to find they sprayed the missed spots as well as the exhaust, back side of my rims and tires, and my brakes, which caused a pulsing in the brake pedal and somewhat diminished brake performance. After complaining, they refunded my money and removed over spray from rims and tires, not without argument, but I had to replace the rotors and pads. Should have done it your way, nice video content, well done.

[@jamesd2289]

Great work, where are u located? Do my tacoma next… How much u charge for this?

[@samstripy1187]

Does it matter if this stuff goes on shock absorbers or drive shafts? Is there anything you should not really put it on besides the obvious exhaust/rubber boots etc?

[@Jarod1941]

To answer your questions: NEVER use this stuff. Period.

[@ibberman]

@@Jarod1941 What to use then?

[@Jarod1941]

@@ibberman Would you paint a Lamborghini with a rattle can? Would you paint a masterpiece with a Q-Tip? Would your wife paint her nails with food colouring? No? Then don't do what these complete morons did. Do your research.

[@ibberman]

@@Jarod1941 I did !

[@Jarod1941]

@@ibberman You shouldn't have painted your Lamborghini with a rattle can.

[@Fatbodypyle]

Don't ever do this to your vehicle if it wasn't rusty before it would be now. Removing the factory protective paint coating allows flash rust to begin and then covering it with the materials used in this video will only hide the corrosion progression. Bad idea.

[@toninocars]

Was it better just to treat the rust with rust converter and then spray top coat with black hard paint spray ?

[@spinb]

@@toninocars I think just using regular paint would be better. The wax undercoatings are good. They don't get washed off as fast as Fluid Film/Woolwax.

[@edgarokras5695]

Could you advise what is better ? Trying to save my 14 y.o. Honda Crossroad

[@spinb]

@@edgarokras5695 I've been using Fluid Film for a few years just to slow down the rot on my 2001 Navigator. My new plan is to wire-brush all the rust and try Rustoleum's Rust Reformer paint, and then spray Cosmoline RP-342 over it. Hopefully it stop the rust and protect the metal.

[@ESLinsider]

Cool. That little wire wheel you are using is a little different than most I've seen on an angle grinder. Looks good for getting into small places. What is that?

[@jackgreen9487]

It looked like an air drill with a wire wheel on it

[@melvin5818]

Huh? Doesn't anyone know on here that rubberized coating speed up the rust?!!! It doesn't let the metal breath and traps the moisture underneath the metal. Look up rubberized coating on KZbin and you'll get many videos of cars and trucks falling apart lol. You only use oil base coating like fluid flim.

[@richardurteaga]

Question can you give me an estimate on how much it costs to do that on a 2008 Jeep Wrangler 2 door at Spiro Automotive?

[@samora3]

looks amazing

[@SpirosAutomotive]

Thank you! 🤙

[@ryolacap]

I'm using steel-it, but wonder if its safe to spay everything under the car?

[@autumna4270]

Guy’s please wear some safety glasses. Those wire wheels are very dangerous. I’ve heard to many stories of welders losing eyes from wire wheels. Painting as well wear a mask. Your lungs are much more important that that vehicle.👍

[@noeeroque924]

Great business idea.

[@andyl9920]

How much would this cost? Meaning how much would you charge to do this job? And did u spray inside the frame where all the holes are?

[@SpirosAutomotive]

Hi Andy, give us a call to get a price for this service. thanks
