Use about a 1/2 gallon, maybe a little more, each time.
But I own a compressor and the gun kit so I can buy the gallons.
IMO Fluid Film is not a less is more thing.
I lay it on thick and heavy.
I spray it inside the uni-body and the tubes that support my factory running boards.
Wish I had drilled holes in my rockers, bought some rubber plugs to close them up, and sprayed in there too.
Going to start but it is a little late in the game for that.
In the Winter I will run the Jeep through the $5 wash bay at the car wash occasionally.
I do not pay the extra $1 for the underside. Fluid Film will eventually wash off.
Every piece of crap on the road will stick to it.
Come April I power wash it off.
The only reason that I don't run it year round is cause I am still working on the underside of the Jeep.
Messy as hell under there when trying to do things.
But I will spray Fluid Film in certain places in April.
One thing I do is use PB Blaster with the Fluid Film in certain areas.
For instance for a couple years now I have been soaking down my suspension bolts with PB Blaster.
And "sealing" it in with Fluid Film. Might actually get my new suspension on this year. LOL.
I do the same with the E-Brake adjustment area.
I just think it is a crappy design being open like that.

When I did washer pumps after I installed them I doused them in Fluid Film.
Hey maybe it will be a little longer before they get all crusty like the ones I removed are. LOL.
Now when I get to a point that most of the work is done underneath I am thinking of running Fluid Film year round.
Apply in April and see what it looks like under there the following April.
If it lasted cool. If not maybe start giving it a lighter spray in April, power wash in October, and lay it on thick like I do.
Come April do it all over again.
Couple things about Fluid Film.
You will never get all of it off the Jeep again.
When I power wash I always see places I missed. Oh well.
I am betting that there is still Fluid Film way up under the Jeep in nooks and crannies from the first time that I did it. LOL.
Also IMO Fluid Film will "condition" metal.
The very first time I did it I noticed that my front diff and steering knuckles were a little "rust red".
Not scaly rust though. Thought to myself come April maybe I will clean that up a bit. Maybe paint it or POR 15 it.
Well in April when I washed it off I noticed that now my front diff and steering knuckles were more a "mud brown".
To this day I never did "refresh" them. LOL.
Also I was not sure how the rear diff breather was set up. All I knew was that hose attached to the white nipple on the uni-body.
So in the beginning I did not Fluid Film that section of the uni-body inside. Thinking gunking the breather in there would not be a good thing.
Later I moved the rear diff breather up to the engine compartment with some hose, clamps, and used the "top hat" breather that the front uses.
Did the same with the tranny and TC breathers too.

So now I could Fluid Film that section of the uni-body and also not worry about gunking up the tranny and TC breathers way up there around the tunnel.
In hindsight, thinking I will change it at some point, I should of attached the new breathers for the tranny and TC on the passenger side.
I don't know why I ran them all over to where the front diff breather is cause they are located on the passenger side already.
The rear diff is already on that side so that I will leave where it is.
