I live in northern Iowa. I'll admit my truck doesn't see as much salt as others in the area because I try and stick to the county roads that aren't salted as heavily and my job has me plowing roads when they are the worst but it does see salt. I also don't wash the underside off until the spring cleaning so the salt that does get underneath stays there.
My wife's truck sees alot more salt then mine because she had to run the highway to get to work and hers is almost just as clean as mine. Only rust on hers is a little bit around the lower A Arms and around the rear springs/axle. I'd say hers is 99% as clean as mine.
Only problem with fluid film is you have to live with the grimy mess, but that's a fair trade off for not having rust underneath.
Yeah, it works but it is very messy. And once you use it, it's nearly impossible to paint that metal ever again. It's very difficult to entirely remove it.
But are you in the rust belt? If that's a midwest salt truck i would be sold.
I was going to get mine done when i first got it but the guy was backed up like 2 months and i forgot. Going to get it done soon but the rust has already started in a few spots so im going to try and clean them up as best as possible with rust converter and a wire wheel.
I live in rust belt ... my 2017 Roush F150 its going on third winter. No rust whats so ever using FLUID FILM ... its does work. Just reapply yearly before winter. $50 for about 4-5 cans will do the trick
