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.

Good product---Works well

Easy to use and effective. Provides excellent rust protection and lubrication, works exactly as expected. It's hard to do better than Fluid Film.

I use it to lubricate the chain and derailleur on my bike. It’s the best lubricant I have found. It is thin but durable and it doesn’t pickup grit the way thicker lubricants would. It’s also to clean and reapply.

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.

“This stuff is the real deal. I use it on everything — car frames, tools, lawn equipment — and it keeps rust at bay better than anything else I’ve tried. The aerosol makes application easy, and it clings well without dripping everywhere. Smells a bit strong at first, but that’s just the lanolin doing its job. Great protection, easy to use, and proven results — the car gods approve.” — Praying to the car gods

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.

Fluid Film is amazing I used it on the frame and undercarriage of my truck, and it left a thick protective coat that really sticks. It stops rust instantly and even helps loosen stuck bolts. The smell is strong at first, but it works way better than other sprays I’ve tried. Definitely worth it if you care about keeping your vehicle rust-free.
