I have had my free sample can of fluid film for a few months now and never got around to using it until the other day. I put it on my $300 trailer hitch I bought this year. Since part of the hitch stays on the truck all year, I wanted to make sure it looks good for as long as possible and won't rust. So that is going to be the test, as long as it doesn't rust in the harsh Michigan winter, I will be happy. I've heard so many good things about Fluid Film that I have high expectations for it. I'm already planning on using Fluid Film on my new mowers in the spring. My only problem at the moment is that I don't have a local place to get fluid film, so I would have to order online. I talked to my Deere dealer about it and they will be looking into getting for the store and didn't even hear about it before. So hopefully they will be stocking that soon after doing some research. I just want to say thanks to everyone who has recommended Fluid Film, I think you have me hooked on it.
