Fluid FilmAerosol 11.75oz

Outstanding Product. Will stay of area sprayed and not run off.

I have been spraying Fluid film on the underside of my car and into the bottom of my door cavities. I bought straw extensions to reach far into any cavities.I tried using a similar product, Surface Shield first. The can clogged up while there was still a lot left inside so I switched to Fluid Film. That's my goto rust protector. So far this is the best rust preventer. Paint cracks and chips from stones kicked up.

The price is several dollars below hardware store prices for this aerosol Fluid Film. I use the product for rust proofing inside the doors and rocker panels of our vehicles. It lasts about forever in those locations. When used where water splashes, it lasts qite a while, but needs annual (or more frequent) re-application. Fluid Film is wool wax. I've used wool wax for decades as a rust preventative. Hit- Buy the extension tube with the 360 degree nozzle for inside rocker panels and doors. it sprays the product evenly and covers completely.

Absolutely the best rust prevention product on the market!

Great for lining the undercarriage of your vehicle to prevent/stop rust. My only complaint was that due to the viscosity/thickness of the spray it starts to get a bit clogged up about 1/2 way through the can (see images). Still usuable but gets very messy and i was only able to get out about 90-95% of the can. I suggest 2 cans for a Truck for this reason. 1 can is fine for a sedan. Recommend doing this about x2 a year if you live on the rust belt or midwest/salted roads.

We use this on our Lawn Mower, works really well to prevent rusting on the chain.

I own a pontoon boat, that I bought about a year ago. The boat and trailer were both 'fixer uppers' although I got a great price on the package. So, I 'refurbished' the trailer recently, as the leaf springs and bolts were all very rusted. Most of it was still fine structurally (but a few nuts had rusted right off) but it was so locked up I had to cut everything off.A co-worker (a senior machinist, who has never steered me wrong) recommend I try this product to treat all the new metal hardware (leaf springs, equalizers, and bolts), as he had some experience with it before. Apparently they had used it as a corrosion preventive on some mild steel metal tubes that were being stored for a while, until they were to be used to cast wax-like material into. However, before they cast the wax into these, they needed to line them with a tar-like substance. However, no matter how much they cleaned the tubes, nor how many nasty chemicals they tried (acetone, and otherwise) to clean it, the tar wouldn't stick to the tubes. In the end, they had to put the tube onto a lathe, and shave a few thousandths of material off. Finally, it stuck.Further, a friend of his has run a non-air conditioned machine shop here in the Florida pan handle, and has had the same piece of mild steel hanging from his ceiling (that was coated with this product nearly 2 decades ago, or so I'm told) and there is STILL no rust on it.So, I coated all my new leaf springs and bolts and nuts with this, and can't find a bit of rust yet. I haven't had it in and out of the water much, but my initial impression is that so long as I keep it coated, then I'll never have to worry about my springs again.Further, I've used a VERY light coating on the undercowl of my newly rebuilt '94 mariner 60 hp. They didn't really make mercs for salt water at that time (motor was freshwater until I got it) so I'm trying to ensure that I get plenty of years out of it (also by flushing it with salt-away every time I use it).Buy with confidence, and I agree - it smells but is much easier and less messy (well, sort of) to apply than never seez******UPDATE*******4 Sep 2012I've continued to apply this product regularly to any and all rust-susceptible parts of my boat. The only parts of my trailer suspension that I see getting rust, and the spots that I missed with the Fluid Film. I rapidly ground them back down, and reapplied.Using this product is a MUST on lug nuts and wheel studs on trailers; even with galvanized or stainless bolts, if you don't use something like this to prevent everything rusting, you will be spending a lot of time with PB blaster and otherwise trying to break your lug nuts free (I just did this past weekend)

Recommended by my mechanic. Pickup undercarriage gets sprayed twice per year. 2006 Tacoma still looks great underneath.
