The Ultimate Guide to Fluid Film Undercoating (NHOU)

[@SouthMainAuto]

Love me a good Fluid Film video 😁

[@bradsbuilds]

Thank you Mr. O! I get a lot of inspiration from your channel. Thanks for watching!

[@davidf9027]

As you said, it’s critical to get under the spare. Before you even said that, I was wondering why you didn’t drop the spare first, spray under and reinstall. That’s what I do, and I would hope everyone does.

[@iTsGamerZ]

ive tried both fluid film and pb blasters surface shield and i like surface shield the most because fluid film comes off once you powerwash it where as surface shield is like hydrophobic and doesnt wash off and sticks really well

[@northerntoyota7584]

If you pull up on the rubber gasket piece on top of the front fenders where hood seals it’ll expose the entire inner fender and make spraying much easier. Learned this after using pdr on a front fender ding.

[@northerntoyota7584]

I used rust check coat and protect with similar wands. Have a 360 tip on a 42” hose. Good for entire inner of boxed frame where access holes are limited towards the rear. The inner rocker panels are hard to access behind the now plastic outer rockers. I was able to get 90 degree wand in seem and fog this area that’s prone to rust. Good work

[@Swindy1794]

My local mechanic has clear or black fluid film, I like the black. I live in Pennsylvania so undercoating is very important, my 2019 Tundra still looks like brand new underneath. 👌👍

[@bradsbuilds]

Very glad to hear that! It really is a great product. Thank you for watching!

[@northerntoyota7584]

Do you find the stuff with the black dye dries out over time? The pro form undercoating in black use to dry out, but not the amber

[@Swindy1794]

@@northerntoyota7584 …. I haven’t noticed any difference between the two… i have it sprayed every fall (Octoberish) and it continues to build up, thicker and thicker with every application. I used to own a 2006 Tacoma and it was completely wasted rotted out underneath. (I never had it sprayed) I had no idea there was a problem until my mechanic showed me. For me at the time Toyota had a recall for that mess and i had it fixed for free…. Still traded it in for my Tundra, i’m not going through that again.

[@chrisE815]

Can't believe he even offered the black tint. I can see using a little bit on a rusty diff or something but that shit makes a total mess when you go to work on the car.

[@nberardi103]

I just applied a half gallon of black fluid film to the underside of my Silverado 2500. I have to get the spray cans with the tube to hit the little holes the spray gun couldn't get into. Surprisingly, living in PA, my 4 year old truck (35k miles) did not have much rust at all. Only rust i really saw was where i layed it on the frame in mud once.

[@madcowusa4277]

Just did the frame of my 41 year old Chevy C10 truck. It looks great a few days later. Ordering more cans.

[@bradsbuilds]

That's great! I love the old Chevy pickups. Thank you for watching

[@amacd08]

I had my 2013 Accord done with Krown the first year (because they drill holes) and Fluid Film every year since. The only issues I’ve had is the car is very messy to work on and the trunk lid drains got plugged from so much undercoating and trunk lid was holding water. Other than that I’ve seen vehicles newer than mine needing rocker panels and other body work where mine just shows a little rust along the rear dog legs. Great stuff!

[@Plekteret04]

I have got a 2004 Ford Crown Victoria and Im going to Fluid protect this now. It will be alot of salty road here in Norway this winter. Has only used some Fluid inside the fenders now. The plastic covers had been removed for the frontsides. I see that I have to get a Fluid film kit with airgun. Its only $300 for the treatment. My friend has a big aircompressor and a grave since he worked with ambulance earlier pvt.

[@tomstarcevich1147]

Love fluid film and PB blaster surface shield 🛡 both are great products i did my 2021ram1500 the first month i got it no rust for me nice vid 😀 👍

[@bradsbuilds]

They're both great products! Thanks for watching!

[@Aerospacer77]

Did you use aerosol cans ? I just bought the same two products in aerosol cans. Today I prepped. Tomorrow I spray.

[@staceyrizzo311]

can the fluid film be sprayed on all the electrical connectors and starter and alternator I'm just worried about the electrical thanks

[@Pendragon501]

I just bought a new vehicle yesterday and I'm planning on doing the whole vehicle in fluid film before I drive it anywhere. I don't have a lift so I'll be doing it via jack stands. I bought 2 gallons of Fluid Film Black, the WoolWax pro series spray gun kit with all attachments, plastic to put on the floor, tape and plastic to cover thew sides, tyvek suit to protect me... I'm not looking forward to this. I also bought the best ceramic coat I could get my hands on for the outside. This thing better last me forever!

[@josephmckinnon3546]

Hello Brad, I'm buying a new 2023 Kia Rio and I live in the salt belt, (Michigan), and I'm wondering what I should do since the car is straight out of the factory. Should I do multiple coatings, black paint, clear coatings underneath the car since the car is brand new? Or should I just stick with fluid film. I want to reapply it every year or so to ensure it doesn't rust, just don't know what I should do for a new car.

[@bradsbuilds]

Hi! I'm my experience, being as thorough as you can with fluid film or other types of oil based undercoating is your best bet. Taking your time and being thorough will make a big difference over just generally spraying the underside. Relatively inexpensive FF sprayguns can be purchased online. If you don't have access to a compressor, you can get a case of aerosol cans and purchase wand extensions for the tips to reach into the cavities. Depending on how harsh your winters are, you could always reapply after 6 months instead of a year. Be sure to be as thorough with the body cavities (quarter panels, fenders, rockers, door bottoms, etc.) as you are with the underside. Thank you for watching!

[@josephpuchel6497]

Hey great job Tundra Dude34 would be proud of you.

[@bradsbuilds]

Thank you! Thanks for watching!

[@Sampsonay]

Do you think fluid film will still do a good job without removing the bottom covers? I dont have a lift so working under my car is a bit difficult. I still was sure to spray all of the visible parts of the frame and suspension and also inside any drain holes in my Civic.

[@bradsbuilds]

In my opinion having something is better than nothing at all. That definitely isn't the most thorough approach, but considering your situation I think you absolutely did the right thing. Thanks for watching!

[@AdkinsDebtDiet]

Why not remove the spare tire to have better access where you say it is especially important to treat?

[@adamcoe]

Not trying to tell you what to do but to anyone attempting this: sweet jesus please wear a respirator WITH an appropriate filter if you're spraying this stuff. It's designed to to stick to steel for months in freezing cold temps. Just think of what even a *tiny* amount of this is doing to your lungs.

[@whatitisnt.]

True although it's lanolin based (sheep). It's not necessarily toxic

[@macfady2181]

[@adammcinnes5615]

I read somewhere that someone mixed a Glade air freshener into their 1 gal can of Fluid Film, so instead of smelling of lanolin, their vehicle smelled like apple cinnamon. I wonder if you could get a similar result by mixing in a bottle or two of essential oils.

Ive used the fluid film and its decent, but i found that waxoyl is a superior product and the cost is around the same

[@VinylTherapy]

On the fence about getting my 4Runner done, my only concern is that I read this stuff is hard on any rubber boots, bushings, electrical connectors, etc.

[@practikyle7054]

I had my 2021 4Runner done with zero issues. I highly recommend. Wisconsin winters did not affect the underside at all.

[@Maab32]

So i coated my truck 3 days ago. Today i noticed my brake making a slight hissing noise when pressed. Coincidence, or did i end up spraying something rubber that i shouldnt have? Could this stuff ruin a rubber seal?

[@IndigoGlow]

Can you apply rubberized rustoleum after using fluid film?

[@bradsbuilds]

No, it wouldn't stick. The whole point of using fluid film is to avoid rubberized undercoating. Hope this helps.

[@torunadwisla]

Great job, can you do my 4runner ? :)

[@waynebinky]

What's your take on the metal in the fender wells that hides behind factory sound proofing material? It is removable, but not easily. Do you spray in behind this or just let it be? Worried the fabric will become saturated and fail.

[@bradsbuilds]

I'm not exactly sure what you're referring to. The sound deadening material that I'm familiar with inside of fender wells is usually a fabric pillow that is just held in with friction. I've also seen plastic wrapped foam material that seals the fender to door gap internally. Either way, both can be moved out of the way if necessary when removing fender liners. The fluid film shouldn't bother them. I know I certainly haven't worked on every car out there so I may have never witnessed exactly what you're dealing with, but I hope my response helps regardless. Best of luck and thanks for watching!

[@richscott2952]

Can it hit the muffler, catalytic converter electrical connections

[@jon8625]

super video--thanks so much!I am going to give this a try at home. What do you avoid besides brakes and exhaust? Lower engine and oil pan ok to spray? Last question: Do you ever remove the hood insulation for access?

[@bradsbuilds]

@@jon8625 thank you! I'm glad you enjoyed it! Lower engine and oil pan should be just fine to spray, but will get quite warm. Very possible to burn off like the exhaust. Generally, removing the hood insulation isn't necessary because there are so many access holes around the perimeter of the hood. It certainly wouldn't hurt though! Best of luck

[@jon8625]

thanks! Should be fun!

[@thecount1001]

too bad there isn't just a FF pool you could drive the truck into and have it towed out after a good long soak.

[@bradsbuilds]

I can't even begin to tell you how many times I've wished that was a thing!!! That would certainly take any question out of coverage haha.

[@LayneSteighlee]

the most important question...why aren't you using surface shield? so much better and lasts longer.

Are there parts not to spray??

[@mikemckenzie3634]

Great video, can you send a link as to where you get your equipment and which brands of equipment you recommend?

[@bradsbuilds]

[@Vova3iLvova]

did you consider adding vanilla extract to fluid film for better smell?

[@bradsbuilds]

@@Vova3iLvova yes. I've tried cinnamon extract before. It does help slightly, but nothing can really conceal the smell of the fluid film. Thanks for watching!

[@GURKS35]

Doesnt the fluid film ruin/contaminate your brake rotors and pads? Oil around those parts is usually a bad thinf

Fluid film does a great job but I don’t like there hose kit for airosaw cans half the material sprays out on you I thought I got a bad one I ordered two more no better. Has anyone else had the same problem thanks?

[@stevereid2760]

Drill a small hole into the spray nozzle of the tip that came with the can. Heat up the tip that attaches to the hose and force it into the hole you drilled. I did this and it works amazingly! Not one drop wasted. Wish I could attach a pic for you, but hope you can figure out what I’m saying. Good luck!

Can you lets us know what psi your were running on the wand with Fluid film? Thanks.

[@terryburke2587]

I'm surprised you didn't wash the under carriage before applying product.

[@engrxtn]

Bought a new car and decided to do fluid film. Bought a woolwax pro gun. Hopefully it goes well. Will be doing my other two cars that I have never coated. I just need the weather to cooperate 😂

I try to avoid undercarriage washes. I recommend yearly reapplications but it depends on your driving habits and vehicle.

[@Tyler-ug1hs]

NHOU didnt sell you on the BossWax undercoating? Why did you choose fluid film instead?

[@bradsbuilds]

I do not work for NHOU. I use MouseOut because I like the idea and added functionality of the product. I've had personal experience with fluid film in the past and I'm happy with the results. Thanks for watching.

[@alexl1820]

Nice work man!! What is your recommendation of a car that is older like 10-15 years and already started to rust? I live in Sweden and over here they throw salt on the roads to keep the roads icefree. Finaly most cars gives up because of all the rust 😔

[@bradsbuilds]

Thank you! This procedure is universal for any vehicle! As long as you can encapsulate the metal/existing rust you can stop the corrosion from starting/getting worse. Just make sure you remove any flaking rust/debris before application. Do you see lots of Volvo's out in your neck of the woods? 🇸🇪 Thank you for watching!

[@alexl1820]

Okej thanks, i will try to undercoat my cars as soon as possible. I have a Mazda 6 (2014) and a Nissan x-Trail (Rogue) (2008) They are getting older but still not too much rust, just on surface. Yes here you can se Volvos everywhere. Its like the most popular car and its used by the police and as ambulance to. The v70 and xc70 (cross country) can be seen everywhere. Sadly they are discontinued right now. Think Volvo stopped the making of pure petrol and diesels. Its all hybrid and electric now....

[@bradsbuilds]

Best of luck to you! Nice rides! It's a shame Volvo has switched over to all hybrids and EV's. They built such great inline 5s and 6s.

[@craigiefconcert6493]

Just to mention, there may be a lot of rust that you can’t see. That’s why they spray inside frame and body cavities. Concentrate on those and also on the brake lines.

[@weloveups831]

Drop the spare and spray the top of those wheels. Thatbis where they really rust.

[@Santiago-je5ki]

How did you get the fluid film to atomize so well? When i applied it it came out in clumps, and i did stir it up. Did you warm it up?

[@bradsbuilds]

Nope I didn't warm it up, it was at room temperature. I think it has to do with the type of gun I'm spraying it out of. If your sprayer has an adjustable fan and fluid setting I'd play with it to see if you could get it to atomize better. Thanks for watching!

[@Aerospacer77]

Where are you located? I live in Chicago and cant believe I couldnt find anyone out here that uses fluid film or surface sheild. Im actually going to do it myself with aerosol cans. Wouldnt mind paying someone to do it right like you with a car lift and an air compressor and spray gun. I have a brand new Tacoma. Thanks

[@Andrew-on5do]

Does this stuff get all over your hands if you need to work on something or collect more gunk on gravel roads since it’s always wet?

[@bradsbuilds]

Yes it can be messy. The dust and silt from the roads will stick to it and create a film on the outside. In my opinion, dealing with the fluid film residue is much better than dealing with broken bolts and flaking rust. Thank you for watching!

[@brkbtjunkie]

How does this hold up when going through a car wash that has undercarriage spray?

[@bradsbuilds]

The pressure deteriorates the product more than the water does in my findings. I would try to avoid undercarriage washes if possible. Thanks for watching!

Looks like your lungs got a coat of fluid film too.

[@bradsbuilds]

[@jerrydrosell]

What size air tip do you spray with your Binks gun? Have you ever mixed in linseed oil with the fluid fil? A lot of people I know do this but I am curious about the benefits of mixing in the linseed oil with ff instead of straight ff?

[@bradsbuilds]

The gun is set up with a 63PB air tip and a 63B fluid nozzle. No, I've never mixed linseed oil with my fluid film. As a standalone product I think the consistency is quite good and I'm happy with the performance. Maybe people mix it in to thin the fluid film? I'm not quite sure. Thank you for watching!

[@jerrydrosell]

Thanks for the reply. Just to clarify the tip you referenced is comparable to a 1.2mm tip?

[@bradsbuilds]

I believe so yes.

[@shaftwood]

Fluid Film can be thinned by mixing in a very small amount of vegetable oil. I do that when it's really cold, to make the Fluid Film a little easier to spray. I haven't noticed that thinning it makes it last any less time on the undercarriage, either. Thinned or not, it lasts a winter, for me.

[@MrLoudog7]

I worry about it getting on brake rotors. Any issues?

[@bradsbuilds]

Obviously you don't want to target the rotors by any means, but any light over spray on the rotors burns up after a few miles of driving. Thanks for watching

It wouldn't hurt to wear a mask when spraying. However, both products are non toxic and I haven't had any negative side effects from either. I keep the area well ventilated with open overhead doors and an exhaust fan.

[@Leon-qc7fe]

I bought the Fluid Film spray kit with two plastic hoses that attach to the sprayer. The sprayer is great. Not so much the hose attachments. The hoses are made of thick stiff plastic and will not flex well enough to do inside frames, doors, hoods. When you bend the hose it collapses and blocks the flow. I found it really a useless, messy, waste of time. It is really disappointing that they make a wonderful product and screw you with a substandard applicator.

No need to disassemble and take off wheels, that's just not cost effect. Just need to drill access holes, then plug them.
