My Cali truck never sees winter BUT as lifetimer in the rust belt, I can tell you without a doubt, fluid film has my business for life.

I read all the reviews, watched the entire internet, chose FF and frankly I was shocked at how well it performs. We purchased the kit that has the sprayer and hoses/nozzles(you could piece this yourself if you wish) and spent a good amount of time on everyone's vehicle(silverados and tacomas) that sees winter. The stuff absolutely can make it through a PA winter, and its absolutely worth it. If you do the application adequately/thoroughly you literally can't tell that the vehicle sees any winter.

Like Charlie said, even the lube properties of it are awesome, I've used it in can form for for latches, hinges, all little fiddly stuff and it performs as good as just about any standard maintenance canned lube/grease etc.

One thing to note: obviously its considered a consumable type application. The important thing for me on it is that if its a front facing part or section(arms, spindle, skid plate, frame/x-member, you get the point), you will probably want to do a slightly thicker application, a second pass of sorts. Sometimes the regular driving wears it away over the entirety of 7-8 months of winter.

Again though, its enough that after 1 season it was an 'oh we should put thicker application on' - problem solved. And for reference to the compulsive folks like myself, there wasn't rust developing at the end of the season, you could just tell the salty road bring just wore it down a bit compared to the completely untouched sections.

My suggestion is to hit it around Halloween and you can easily make it through March/April.

Out here in So Cal...Big Bear in particular...they are now using brine on the roads up to BB when it snows. (Cal Trans acknowledges this on their website)

I had surface rust EVERYWHERE in a couple of days of driving around up there last winter.

I douched the entire underside w/ Berkbile Salt cutter....then coated all the rust w/ Eastwood Rust Converter after it dried. Now no rust.

This sucks, but it is what it is....now I wash my truck every time I come down from there in the winter (my daughter lives up there and has a 2nd gen that has same surface rust prob).

I'm considering a spray on Lanolin product, or the Cosmoline as mentioned.
