The end-all Fluid Film thread

Interested in using fluid film for some rust prevention on the bottom of my jeep and have a few questions.

1. How often do you have to re apply, if at all?
2. Is there anything on the underbody I SHOULD NOT spray?
3. Any other tips or tricks from your experience?

Thanks

Good questions. I need to tackle this soon too. I'm interested to see what kind of prep work is needed, if any, as well.

1. I started using it very sparingly back in February I believe, just on shock mount and CA points. I noticed how new the material made the surfaces appear, so I went ahead and sprayed more on other areas around the axles, dif covers and so on. I pressure washed the underside to remove all the dirt and grime I could and on about May 1st I applied a full can to the underside, everything but the exhaust, and brakes of course. Took that Jeep to the beach for about 12 days, ran deep sand, wet sand, salty sand everyday. All added up probably 250 miles of beach running. about a thousand miles of road. All I had to do to remove the sand from the material was a garden hose and just rinsed it clean. The underside looks better than it has in a year and after that rough month the film is still there (not as much but still there) This material also has a good creep characteristic, it levels itself out after a day or two.

2. The exhaust, brake disks and pads are things I would not spray with it.

3. Hinge pins, High lift jack mechanisms, and on and on. It is lanolin based and does not hurt rubber. You can spray the inside of your bumpers, wheel wells, makes cleaning off mud and dirt much easier.

Fabulous stuff.

That's a good point. I was planning on just power washing the underbody, but curious if more is needed too

I have used Fluid Film but I like CRC Heavy Duty Corrosion inhibitor, 06026 -- Heavy Duty Corrosion Inhibitor, 10 Wt Oz
better for corrosion protection, it has a heavier more durable coating than Fluid Film

Thanks. So you just crawl on under and spray the underside of your vehicle? I've never heard of this. I have heard of farmers "oiling" their equipment... same thing?

I've been using WD40 twice a year on my jeep underside and it seems to work great here in the salt ridden North East.

I'm curious about the prep work. I have some spots around the joints that have rust showing, should I do something to clean that up before spraying with fluid film?

Thumbs up

As with any rustproofing treatment-you want to pre-clean the area as best as you can. I've posted about Fluid Film before. I can't praise it enough!

I use it on everything where rust/corrosion is an issue. I especially like the fact you can use it on plastic & rubber parts. It's available at some national auto parts stores. I have found the best prices on eBay for case lots of the 11.75 oz. spray cans. Once you start using this stuff you will be amazed at how many things you can use it for.
On the spray cans, check out the tube/hose holder molded right into the cap. Ingenious!!

I use fluid film religiously on my heavy equipment from tractors and implements all the way down to the lawnmower deck. It makes all clean-ups a garden hose affair and saves a ton of time between jobs. The underside of the vehicles just came as a natural extension of use. Beats the heck out of tooling up the power washer every day.

How would you recommend "pre-cleaning" just cleaning the dirt off with a power washer and some simple green, or should I spray some sort of rust treatment on first (any recommendations)?

I usually spray any bolts or areas on the frame where there a are welds or holes. A lot of the components like the axles have a real bad paint job from the factory, for those I paint them first with POR-15 Top Coat in chassis black, TOP COAT

Thanks for the tips. I'm going to do this when I get some time. For those who were asking, I'm going to get the fluid film from lowes

Buy a kit. Most cost effective. Apply annually and rinse off the undercarriage periodically without soap. The kits allowed me to drench 2 cars with about 3 more left over. pancake compressor and spray gun is best but wear a respirator as it is lanolin\oil based. Also you will lose a pair of old jeans an t-shirt cuz it smells like shit going on and subsides after 3 days. Leaves a clear skin semi-wet coating. Best stuff ever. i use it on everything, snowplow, tools, etc.

I've never done the entire underside of a vehicle myself. I watched a guy do my pickup and he really didn't do any heavy duty cleaning ahead of time. The truck was 2wd and wasnt' very dirty underneath.
Obviously you will want to get as much mud off as possible and a good spray with a pressure washer won't hurt. I had my truck done about a year and a half ago. Can't update you on how well the Fluid Film held up as I traded the truck a year ago this past Feb. You might want to check with someone local to you that uses Fluid Film for undercaoting and see what they would recommend regarding pre-cleaning. More and more shops (especially in NW Pa.) are using Fluid Film instead of used motor oil. In regard to any rust pre-treatment-that would depend on how much if any preexisting rust you may have. If it's only light surface rust, they say Fluid Film by itself should take care of that.

I have a 2013 and started looking into rust prevention after climbing underneath and seeing how bad it looked after 3 Wisconsin winters. I cleaned the under side and then took a wire brush to the rust to get as much off as I could. I went whole hog and got a rust inhibitor kit from Eastwood (there are others, POR15, Rustoleum, etc) and sprayed pretty much anything metal on the under side. Then a top coat paint for further rust prevention. I let that all dry good, washed under side and then applied the Fluid Film to most metal surfaces underneath. There are several threads on here that mention applying it every 6 months or so. Being in a winter climate I plan on doing it every fall before the snow and salt fly and again in the spring. If you have rust, I would recommend spending the time and taking care of it best you can before applying Fluid Film. After that is should be a snap just reapplying FF.

I love fluid film. I use it in the fall before salt is needed on the road, then I wash the crap out of it in the spring after the salt is gone and re-apply. Something that bone collector mentioned that I completely agree with, is that besides its anti rust ability it makes cleanup after off-roading much easier.

Doesn't matter what model Jeep

Just to add my 2 pennies to the thread (even though I own a TJ) - Fluid Film is excellent. Very effective prevention / rust inhibiter.

For example;
I sprayed it on my already lightly rusted spring perches in the Fall, 2014. After this long, harsh Jersey winter, the Fluid Film is still there with no sign of corrosion. It keeps the surface moist and 'sealed' from air, inhibiting the continued spread of rust or development of new corrosion.

Bless the company that developed it!

I wasn't so sure if I was supposed to cover myself as well, so that clears that up

So does this Fluid Film stay moist/wet, like grease? Or does it dry?

its good stuff no doubt i use it all the time just the price is a little expensive. I use bar and chain oil for underneath my jeep. But if you got the money fluid fil is the way to go. I laugh so hard when people spray wd 40 for rust protection.

I've only sprayed once so far, before winter. I'm going to pressure wash and reapply before the weather gets cold. I've ready 6-12 months depending on conditions.

You can spray everything but brakes. Stuff that gets hot will smoke after the first start up.

I just roll around under the rig on a creeper and spray everything! There isn't much too it. Enjoy the protection!

For it to be properly effective, it should look "wet". So if you've sprayed an area and later on, it looks dry, spray it again.

I am using this product - Rust Cure DIY 880ML Pack

Much better than anything else I have found period. $60 and you are all done.

Works on all materials - won't harm rubber, brakes etc... And non toxic.

Can apply even when the car is wet. Amazing product.

Thanks...but I guess I'm wondering if it actually stays wet. Or does it dry, but just has a wet/glossy look to it?

If you were to apply it and leave your jeep in the garage it would probably stay wet. Otherwise it picks up all the sand, salt and road grime and turns into a thin greasy paste.

Will one spray can (11.75 oz) be enough to do the whole bottom? Or would I need more?
