My TJ is essentially rust free, and I would like to keep it that way. One of the next items in my rust prevention to-do list is to protect the inside of the frame. The two leading options for this are Fluid Film and Eastwood Internal Frame Coating.

What I'm looking for are your thoughts on the coverage and application for the product that you chose to use. I would like to hear first hand accounts from people that have actually used either (or ideally both) products.
 
I actually use both. I use Eastwood for the frame because it comes with a very handy long hose to reach those very hard to get to places inside the frame.

I use the Fluid Film on the entire underside of the chassis and suspension.
 
So did you only choose the Eastwood for inside the frame because of the hose? You could have used the same hose with the fluid film.

Yep, this is correct. Truth be told I think that you could use fluid film inside the frame with great success. I simply went with the Eastwood for inside of the frame because of the long hose it came with.

The fluid film is fantastic though. If you watch the videos on YouTube of tests they do with that stuff on metal in saltwater, it really does work!

Yes, people all over the northeast use Fluid Film for inside the frame too.

I would use it inside the frame too. If I could do it again there was really no point in purchasing the Eastwood other than that long hose it came with.

The Fluid Film really holds up so I imagine they both work as good as one another. I'm sticking with Fluid film from here on out and applying two coats a year which should be fine.
 
I put a whole gallon of fluid film on my tj , drilled drain holes in the frame. . Then Ran a hose down the frame and filled the frame with slop oil...covered the acess holes with gorilla tape ....seems to be holding up...

We used some stuff down in the shipyards that was called "flowcoat" IIRC. It was used in the areas that we couldn't get to when we painted ships. Fill the void and pump / drain it out. Nasty, smelly junk that absoulutly killed corrosion and protected steel from a really harsh enviroment. Might try to find out what that stuff was and try it on the inside of the frame just for giggles. I know that BuShips required it's application in certain areas.

I cleaned the inside/outside of my frame really good, then used the Eastwood internal and external. My plan was to fluid film it as well before winter, but I missed my chance. I plan to do the same this summer, redo the internal and external of the frame, then use fluid film from that point on.
 
I just ordered three cans of Fluid Film and the 360* nozzle yesterday. I had a little "incident" on Sunday when I got stuck in some deep water and that kind of kicked me in the butt to get the project done. I also drilled some small holes in front of the rear control are mounts to allow for drainage, and spent most of Sunday cleaning the carpet and the chassis.

I love Fluid Film, absolutely love it! It really does work great if you do 2-3 coats per year.
 
The fluid film melts into the rust when nothing else will stick...not much sense applying anything that dries to loose material

Chris, how does this differ from WD40s Corrosion resistance stuff? Just trying to see if it is close to the same thing.

WD40 is simply fish oil. It's staying power wouldn't be much different that cooking oil. Fluid film is a lanolin based and for some reason, it hangs in there a long time. At one time, it was specifically called out in International tech bulletins to protect wiring grounds on exposed frames (class 6-8 trucks).

I was thinking about the application of liquid Fluid Film (not aerosol cans). Most plastic garden pump sprayers (the cheaper kind with plastic bendable wands) have the usual adjustable tip. If you remove the outer tip, the liquid shoots out 90 degrees on two sides. Experiment with straight water and various pressures to see if your garden sprayer will do this with the correct pattern and volume. Might work well for inside the frame rails through an access hole.
 
that was my issue with fluid film. My jeep doesn't see the snow and salt anymore, So, I applied eastwood on the whole thing. Lots of it. Used four cans of the internal. 4 cans of encapsulator and 3 cans of chassis black. There were a few little spots that I need to spot blast and re hit due to lack of prep on my part. The eastwood stuff, has been on my frame for 4,000 miles in a mixture of driving and has held up great, except for a few tight spots I didn't prep as well. I have a small hand held open air sand blaster, I will be blasting these spots in the spring and re applying eastwood. I also intend to do additional coats of the internal frame coating.
