Fluid film advice

Hello. I am going to fluid film the truck for the first time. I plan on getting under and hosing it all off, letting it dry for a few days, then spraying it on over the gravel driveway. Seems pretty basic but any tips or advice? Thank you for your time.

Coonman will soon be here with his large amount of advise on this subject.

Is this for the trapping vechile?

Get the gun that goes on an air compressor, not the rattle cans. Make sure it comes with the long 360 degree wand for inside the frame and body cavities. Spray anything the rusts that doesn’t get hot like the muffler or brakes. Body, frame, brake lines, ect… Get the 1/2” plugs and drill holes into your doors and any cavities that can rust out. What truck is it, how old, and how much rust does it have already? Also, why are you coating it now? Fluid film wears off and will need to be reapplied annually. If you have salt on the roads in the winter, applying it now won’t help as much as it will if you coat it soon before winter.

How much are paying for fluid film, turkeytime?

07 Toyota, light surface rust underneath, frame looks fine. Out of warranty for Toyotas frame recall so trying to increase the longevity. I was going to buy it on Amazon.

What's Amazon's price for fluid film?

Wonder how much dust and dirt will stick to that undercarriage? To each his own.

I would try to do it over something other than a gravel driveway. You will be rolling around on the ground in all sorts of ways trying to spray inside all the undercarriage, inside the frame, and the interior of all the body panels. Laying on the gravel for that long is going to be painful. If you do it on a garage floor, it won't cause any harm to the floor. You can just mop it up or wash it with soap and spray it off. It will be fine. I suppose it could stain a concrete driveway, though.


I was able to reach every area of my Ram 1500 without drilling any holes. I had to remove some tape from the underside of the rocker panels. But once I did that I could get inside both the inner and out rockers. Then I just put some new Gorilla tape over the holes.

Take out wheel well liners if you have them. Take your time and work hard to get inside all the little nooks, crannies, and cavities.

Running each end of the truck up on ramps will make things much easier.

I bought the spray gun and a gallon of Fluid Film. I also bought a couple of the spray cans. I'm so glad I got the spray gun. I feel like I thoroughly coated my truck and only used about 1/2 gallon of the product so I have enough left over for a second application.

Even though it's been eight months since I applied the Fluid Film, when I leave the truck out in the sun I can still smell it. Personally, I like the scent and it also gives me confidence to know that the product is still there and probably still seeping and creeping all over my truck's insides when it gets good and warm. So, I would probably be tempted to apply Fluid Film at the end of summer, and let some of the early autumn sun and heat warm up the oil and have it soak in real good before it gets cold.

It took me about four full hours to apply Fluid Film to my truck. That's putting it up on ramps, pulling wheel well liners, getting access to doors and tailgate - everything. It was a big, dirty, tiring job. But, I feel it was well worth it. Not easy, but I have confidence in the product and confidence that it was applied thoroughly. Wear old clothes, a head lamp, safety glasses, and a dust mask. I think the first one or two times applying the product will be the hardest. I don't think the product will wash away from the inside of the doors, tailgate, etc. after just one or two years. I believe annual repeat applications will need to be less thorough to maintain protection over the years.

Also, I would recommend getting a pressure regulator you can adjust right near the spray gun. I picked up a short 18" extension and pressure regulator with gage for a few bucks and attached that to the spray gun. It sure makes dialing in the spray pattern a lot easier.

Fluid Film is fantastic product. It does a great job at rust prevention all over my shop.

I would think that oil would work also

Wait till fall.

Pressure wash first and make sure it’s dry before you spray.

Used Fluid Film on a new Yamaha 4-stroke outboard. Sprayed everything under the bonnet. Crab boat sat in salt water all summer for five years. Finally sold it. No rust at all.

Sprayed the hood hinge and springs on a new Chevy truck. Salt air works on that part especially bad. Seemed to work. Roof rusted before anything else. Inside of tail gate would be a spot I'd hit.

I’m sure glad I don’t have to worry about my trapping vechile rusting. Sounds like a pain in the rear just keeping your vechiles from falling apart.

turn your compressor down & it goes on cleaner, not as much gets atomized. i spray at about 12-15 psi play with the nozzle till you get it where you like it. i have also heated it up in the microwave in the plastic bottle in cooler weather like fall. seemed to spray better & still clings good.

They make it black colored now and it is much easier to see where you have coated and missed....

Took words out of my mouth. I used the black, you really want old clothes with that. Ask the parts store for a engine fogging tube for aerosol cans. It's 3 foot long and sprays 360 degrees. If you use aerosol cans. I use a combo first time, only aerosol for touch ups.

Great advice, I would get gallon it, a year ago, $45, an good sprayer, I would only use the fluid film, it last along time, I didn't have sprayer, aerosel cans, u be spend over $150, I used paint brush an from Oct, it still there in places on frame an above an by donut , still some fluid there

I would definitely park the truck on pavement, cement or any surface where you can use a creeper to get under the truck. I don’t have a creeper and I’m rather sick of the process. You will be rolling around and accessing all points under your vehicle so the creeper will make the whole process easier on you and faster.

I bought a truck from Oklahoma and have had it up here for 2 winters, both with fluid film applied. So far, so good!

Just did it this morning. I won't have time this fall. In case anyone else wants a try:
My ramps may or may not be strong enough for the truck so I put the rear end on jack stands, on concrete, and a creeper. Next time I will get ramps. I am not large and could have used more room. I bought the gallon and used about 1/3. Spray gun I got on Amazon had a pressure regulator with it. The mess wasn't too bad.

I do mine after a big rain and drive the truck through the water puddles so you can hear it beating up under the floor pan the go to the car wash and get the under car wash. Put fan under it for 24 hours the go at it.......jk

Does it work over rust?

it blocks the air getting to it so it slows it down more than doing nothing

I put mine over rust. Trying to slow down the process.

I use it on our quonset building where the metal meets the concrete trough. It begins to rust there and below grade.
