Fluid Film 11.75 oz. Spray 3-Pak, Spray can Extension Wand, Bonus Number 1 in Service Wallet Size Tissue Pack

Covers the underside on my vehicle very well to protect and prevent rust, does drip when first applied but that’s well known and expected.

Works great, wish I didn't have to buy with THREE cans, product is great, doesn't run, extension makes this a perfect item

I used this kit to undercoat my 4Runner. No problems at all. Time will tell, but this product has been well-reviewed many times regarding efficacy .

it worked good for me . I saw people with the messed up cans photo and i think peoples drain plugs are clogged . You have to have holes drilled in inner panels , the only time i got the product on the can like the photos was when the product was applied to much .. also depends on the temp you are applying the product right now its 70 degrees

I looked for a product I could apply myself. I bought a 2015 GMC Sierra 1500 SLT with 37,793 miles on it in January on a day that was raining,sleeting and snowing all at the same time. I didn't look under the truck because of the weather and the low mileage. The truck didn't have a mark on it but it did come from Michigan. I got the inspection sheet and Carfax for the dealer. Plus I ask the salesman if there was any rust on the frame. He told me know there was not. A few days later when I could get it in the garage I was shocked at the frame rust on the truck. There was a few small places on the bottom pinch seams at the bottom of the door. I bought another brand to treat the door rust and painted over it. Then I look for every product to see which one did the best job for treating the rest of the truck. I did clean the frame off and paint in with a rust protective spray paint but some rust still bleed though after a rain. I bought the Fluid film and treated the whole truck. inside every crack and panel. It killed the rust and left a nice low gloss film and everything. I have drove it though several rain storms and it still looks new on the underside. I bought a gallon can and used a electric spray gun. I did have to put a quart at a time in the microwave and heat it up so it would go though the spray gun. I bought The spray kit that had the wand to spray inside the doors, tailgate and inside the frame. These trucks cost over $60,000 now. Using fluid film that cost me about $90 so far is well worth the money. This product is easy to apply and doesn't cost that much. I,ll be using it from now on.

Apply under your car and in the doors and rocker panels to add years to it!!!

First time using fluid film. Have rust in rocker panels that's out of control and used this because I've been unsuccessful at any other rust treatment. Anything else I've used has worn off and continued rusting after some time. With fluid film I can just spray it on every 6 months and it will stop the rust. I wish I would have put it on before the rest started but I was too late. I also used it for a squeaky suspension component and it works well for lube and has good longevity. It's smells a little but it doesn't bother me since it's on the outside of the vehicle. That smell eventually goes away.

Tried this because I wanted real fluid film as cheap as possible. The fluid is fine, but the attachment for the extension nozzle is trash. I'm assuming it's not made for these specific cans. All 3 cans leaked profusely while using the extension. Had to wrap top of can in rags to use. Ended up wasting probably half a can through dripping. Used soaked rags to rub some metal parts after.
