Fluid Film® Aerosol 11.75oz

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!

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

It works, but it has a pretty pungent odor (initially) and leaves a thick, sticky residue. I know that's how it does the protecting, but I would probably try to find something less smelly and sticky.

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.

I have a balcony with a diamond plate metal floor. Unfortunately because after the zinc coating comes off which doesn't take long the rust starts to set in. Over the years I tried rust removal, rust prevention painting but nothing really worked to inhibit the rust. I started looking around for solutions that were more permanent and came across this. Reviews about its use especially in marine areas got my attention so I thought why not try it. I did a light angle grinding of the balcony floor to remove most of the heavy rust with a wire brush attachment. Then I just sprayed the fluid film on top of the rusted spots, giving a good coat. Not going to lie it stunk! But the smell went away rather quickly and I was surprised because the balcony is south facing and gets tons of sun which I thought would make the smell worse. On top of the rusted spots around the perimeter areas of the balcony I placed artificial grass as a border and then on the interior I laid interlocking 1' sq Trex deck tiles. The jury is still out as to how well this will work because I just completed the project last week. the only concern I have is that the artificial grass lays directly on top of some of the rusted spots but nothing sits on top of the grass, and I'm planning on reapplying the fluid film more often there to make sure that those areas are more protected. Will update this review in some months once I remove tiles to check the rust.
