Best Car Undercoating? Let's find out! Is Flex Seal the Best Rust & Salt Protection?

FLEX SEAL, WD-40 Specialist Long Term Corrosion Inhibitor, Fluid Film, Corrosion X HD, CRC Heavy Duty Corrosion Inhibitor, Corrosion Block, and used motor oil tested as car / vehicle undercoating for resistance to rock chips and corrosion (oxidation / rust). Various deicing products, such as salt brine, are used on roads to make them safe for driving, but these products cause corrosion. Hope this video helps you select a product that's best for your circumstances. I purchased all of the products with the generous support from Patreon supporters.

I use the fluid film to coat my table saw to keep the moisture from rusting the table. It does an absolute fantastic job of preventing surface rust.

[@ProjectFarm]

You are welcome! Thanks for sharing.

[@Ritalie]

You know I learned something from working alongside commercial steam pipe welders. It turns out that insulating steel and cast iron with a blanket or wood box, or fiberglass insulation, completely stops 100% of rust, by stopping 100% of the condensation. If you put a flat sheet of particle board over the entire top of your tablesaw, it won't rust AT ALL, even with 95% humidity. I stopped putting oil or fluid film on my cast iron table saw top, and started just keeping it covered with 2 slabs of particle board. My hydrometer said my shop had 95% humidity in the middle of winter, with absolutely no heat. I'm mad that nobody ever explained this to me, an air tight wooden tool box or blanket will prevent rust, by preventing warm air hitting the cold steel tools. I haven't oiled my table saw in 3 years now, and it still has no trace of rust. Oil + insulation = zero possibility of rust.

[@Internetspaceships]

My car is 21 years old now and i have it coated professionally every year with Fluid Film, i am amazed how good it is at keeping rust at bay. Especially with all the salt on the road during the winter. Its not really a good penetrating oil though so i just buy a few extra cans and spray the underside extra thick then drive on some dusty roads to make a sticky mess under the car that will repel anything :) . By far the best application for it is in the car frame/inside the chassis to keep water out so the rust wont eat it inside out.

It's meant to protect truck beds from dents and scratches and keep them looking nice. Nothing about it being meant to stop corrosion. It only stops incidental corrosion by making sure the stuff you slide around in the bed doesn't wear away the paint.

The advantage of fluid film is that it is very penetrating. It creeps into the pinch welds at the edges of doors, fenders, and any places where seam sealer has failed. This is an important property. For any accessible surfaces, a coat of POR 15 paint followed by tar based brush on undercoating can give 15 years of rust free protection in salt. The ultimate, but it's a pile of work. l

I like how you reply to almost every comment, even three years later. You are the GOAT for that. Used engine oil alone doesn't do the trick for inhibiting corrosion; it washes off too easy. I've been using a blend for years consisting of mainly used engine oil, paraffin wax, and calcium-based grease. I heat and blend it in a rice cooker and spray it on hot. In the right proportions, it has a dropping point of 30C, which makes it flow and creep in the summer and gel in the winter. It's successfully protected both of our vehicles, needing only touch-ups every season.

We had older cars with worn engines, he said this mixture would keep them running better for longer. It seems like a lot of additives to me, but maybe it is a good trio for old engines. Just food for thought.

Thank you very much! Great test idea on synthetic, restore and dura lube.

I love cars and am fortunate to live where they use sand and I'm never in the snow. Have an 05 Mustang with zero rust and it's gonna stay that way!

Thanks for finally doing a fluid film video. Yes it does have to be reapplied once in awhile depending on area of exposure. The one thing I didn't say on my last comment a year ago is that it also repels water. It does an excellent job of keeping your locks from icing up. Yes I'm from Canada lol. Great job on your videos I'll keep on watching.

This was a great video that saved me about $600 I would have paid for the dealer to undercoat a new Tacoma. In the past, I have always relied on Consumer Reports for their testing. Now Project Farm is the first place I look to see if a product has been reviewed. Thanks -

When I was still in the Navy we would coat are aircraft in Fluid Film everyday after a fresh water rinse while on deployment to protect them. We would use a lot of it on the magnesium gear boxes and steel screws and put a light coat on the aluminum skin. Trying to keep aircraft from corroding with salt spray everywhere is a pain and Fluid Film was a life saver. Glad to see it do well in your tests.

[@ProjectFarm]

[@larrieelieff9064]

Great videos! Really enjoy your work. I read through many comments and excuse me if someone has already mentioned this point. I have searched out the best answer to the corrosion problem since 1976 and since I live in Ontario it has been a long battle. The winners in your showdown definitely resist the wash off better than my choice of Fluid Film.BUT .. and this is huge, how do those products react with plastic wiring, rubber suspension, body mounts and rubber door seals. Fluid Film should be the winner of this contest on those points. Not only is is non staining, non toxic and rubber friendly is softens your hands while you are applying it. LOL. Love your work, keep it coming.

I used Fluid Film on a 22 year old snowblower before last season. I can attest after it sat in a hot shed all summer and finally pulling it out last week the fluid film looks like I applied it yesterday. Its lubricative properties are still holding up the on the chute and universal connection. Good stuff!

[@ProjectFarm]

Thanks for the feedback.

[@ALAPINO]

I'm very happy that your experiment has reflected my own experience with Fluid Film. An added benefit is that Fluid Film is food safe and certified for use in agriculture and food production: a fact once important to me in the past. These days, Fluid Film will always have a spot in my cabinet but I have found another product that is half the cost and 95% of the effectiveness. Rust Check is my go to for vehicle coating. I apply a few cans to my vehicles costing me $20 per season. Edit: Rust Check is also lanolin based, like FF, but is not food safe. It creates a soft waxy barrier like FF.

[@ProjectFarm]

[@mikefennema5561]

Here in Canada, rust proofing products are rediculously expensive, so I started mixing my own. Using a drill powered paint mixer, mix one 400 g cartridge of Valvoline grease with 1.8 to 2 quarts of chainsaw bar and chain oil. For inner panels, a little thiner exterior surfaces a little thicker. I spray with a pneumatic undercoating sprayer.

[@richcombs4805]

Neat idea...how long have you been using the mixture, does it stay on well in high splash areas, does it creep a little bit? Not too much cheaper just below you in salty northern NY. I've used Ontario based CF3000 in doors, rockers, panels, cavities, trunks and like it's ability to creep.

[@whitegoodman7465]

Krown rust proofing isnt that much and they spray it inside the body panels too..its $139 once a year.

[@TandD1w]

This is an old one and I don’t recall if you’ve done a round 2 yet, my two suggestions are Fluid Film Chassis Black and Cosmoline. RP-342 is the military grade stuff. I recently bought some New-old-stock parts for a 1934 Dodge. They were coated in Cosmoline and still looked like new! Incredible for parts that might have been on the shelf for 90 years. The chassis black behaves much like regular Fluid Film but I think it might have some rubber mixed in as it covers like Flex Seal.

I live in Upstate NY. Been undercoating my car with Woolwax (same as fluidfuilm, Sheep Wool Oil) for the last few years. Great results. Barely any Rust. I'm using the Black Woolwax. A Bit heavier in Viscosity than the regular. Also easier to see where you coated. I use a cheap compressor and 50$ Woolwax sprayer gun. Goodluck all !!!

[@ProjectFarm]

Great feedback! Thank you

[@richcombs4805]

Just bought my 2nd and 3rd case of woolwax. Gonna use up my two cases of RP-342 on my '18 Camry and then overcoat with woolwax. How has woolwax done for you on any rust spots? Does it seem to keep them from progressing?

[@owenconnolly3041]

@@richcombs4805 Yes Rich for sure it has stopped them progressing. I own a 1999 Acura 3.2TL. I got it 3 years ago from a Lovely old lady of 93 who was my neighbor and sadly passed away. She had garaged it every day. This was in Boston MA. Then i moved to Rochester NY for work. It had a few very small rust spots underneath originally. Usually bolts or brackets or such off probably inferior metal. but i can honestly say they have not progressed at all since. My dad owned an old Dodger Ram truck previously. I done a lot of por 15 painting on it. I had mixed results after a lot of work A lot off scraping and difficulty painting. The beauty of the Woolwax or Fluidfilm as everyone says is that it moves. When the por 15 paint chips or flakes off from underneath you will have very rusty areas. But the Woolwax will just drip over that exposed area when the car chassis warms up again. And recoat that exposed area and keep it from Rusting. It definitely works. And it don't get much Saltier than an Upstate NY winter. This liquid salt is the main culprit now. Anyways sorry for the late reply and Goodluck Rich !!!! \
