Fluid film is AWESOME
This review was not about fluid film, although I will tell you that it met my expectations, who is easy to apply as well worth the money. The delivery was fine. Nothing against the driver, but the way it’s packaged, it’s a joke. Twice I bought this from different sellers and twice it showed up with the lid partially smashed and popped open with the contents leaking out. PLEASE DO BETTER WITH THE PACKAGING!!!!!

    This is best for under mower deck, anti-stick compound

    Reviewed in the United States on June 6, 2025

    Verified Purchase

    This Fluid Film has worked the best for preventing dried grass from sticking to the underside of a mower deck. This allows grass to be scrapped off with ease, even 1 day later. This past Spring has been very wet, and can create difficulty scaping wet grass clippings out from under the deck. Especially if time does not allow you to remove in a timely fashion. This is also a great rust preventative on metal. I highly recommend Fluid Film.

    This stuff is awesome

    Reviewed in the United States on July 2, 2025

    This stuff is awesome. I live in Wisconsin and there's a lot of salt on the roads in the winter. I spray it on in October and wash my vehicle probably 10 over the winter and by the following spring there's 80% still on the frame. Tip, if you spray in on warm it up in a crock pot first, much easier to spray. I been using it the last 3 years and will keep using it on all my vehicles.

    Must-have for new england winters

    Reviewed in the United States on December 23, 2024

    Verified Purchase

    This keeps my vehicles rust-free really well despite the copious amounts of road salt here in northern new england.
    You have to reapply every year or twice a year because it washes off.
    As far as I know this is also non-toxic.
    Other than washing off after a few months it smells bad for a few days after spraying on.
    Don't spray it on rubber parts because they'll swell.
    Best to apply when its still 50-60 outside so it flows well and easy to spray on.

    Great product to keep your vehicles on the road longer!

    Reviewed in the United States on August 16, 2022

    Verified Purchase

    This product is a must if you live in the Northeastern part of the United States or anywhere rust may be a problem on your vehicles. Great on frames and structural components, inside rocker panels, and can even use as a wheel and tire shine or to freshen plastics and oil-resistant rubbers. I apply at least once a year on all my vehicles before Winter. I also use it regularly for protection inside panels whenever I weld on new rockers or anything else that may be enclosed. All of my vehicles are 20+ years old with high mileage and this product helps keep rust at bay. I use it on everything. Even just to clean parts and rusty bolts!

    Great value. Great product.

    This was way cheaper than buying individual aerosol cans. A bit more difficult to apply but like a quarter of the price. After applying it, I understand why everyone says to rust proof the frame of your Toyota truck with it.

    Excellent Corrosion Protection

    Reviewed in Canada on November 28, 2024

    Verified Purchase

    It's Fluid Film… 🙂

    Since it's lanolin based, it breathes and is self healing, unlike some other under coatings. I've used this for a couple of years and it completely stopped the spread of rust underneath my Corolla. Good stuff.
