Fluid Film Aerosol 11 75oz

This is the stuff if you want to undercoat your car or protect metal from the elements. Goes on easy and has staying power. Its not permanent and will eventually come off if subjected to a constant or high pressure water stream. Otherwise its a great product. Read more

This stuff is awesome!! I sprayed the entire frame and everything underneath my truck with less than 1 can. It's been on all winter and still looks like it dogs when I applied it. Sure for way to keep rust at bay. Read more

This is the best product we have found for putting on our PTO shafts so they come off easy. We’ve tried other products but this stays the best. Read more

Great for touch-ups between applications and for small jobs. Fluid Film is not a permanent coating and will need regular treatments. It seals out water without sealing it in causing more rust like traditional undercoating. I was replacing my battery and noticed rust forming on the brake lines that run underneath the battery tray. This will help keep the rust at bay until I get around to replacing them. I use it on the bottom of all my vehicles to keep as much salt off of them in the winter. Read more

Works really good, just shake it up a bit and start spraying. It sprays pretty generous so you won't need much. After a couple days I checked on it and it stayed the same consistency as before, and it covers all the car underside parts well. Make sure to wear gloves, glasses, and a mask when spraying. Definitely don't recommend getting the aerosol in your eyes or nose. Read more

This stuff is great. Spray over rust or on new metal and let it gets as dusty as possible. I do hot laps one dirt roads. It makes it last longer on the surface. Read more

I recently tried out the Fluid Film® Aerosol 11.75oz on my car, and I'm glad to report that it's been effective in providing rust protection. The application was easy, and the results have been great so far. Plus, it's handy to have around for other metal items in the house. By the way, my cat knocked over a plant while I was applying it, but thanks to this product, the metal pot didn't corrode! Read more

I have a diamond back bed cover on my 2025 GMC Sierra. This product was recommended by their service department. The temperatures have been falling into the teens here and I was having trouble with the bed cover locks and weather stripping freezing. I shot some of this product in the locks like recommended. It got down to 15 last night, the key went right in and the locks opened up easy this morning. I also took some and sprayed it on a towel and wiped down the weather stripping and that opened with no issues as well. It's around the same price as WD40 and PB Blaster. It smells a bit worse than those 2, but not unbearable by any means. Seems like a good product to put in the rotation. Read more
