Now I know why Fluid Film works so well. It consists primarily of lanolin. I know lanolin is used extensively in underground mining to protect electrical connections on machines. The underground mining has severely corrosive operating environments and good old natural "ram jam" beats anything else out there for corrosion protection.

So I just applied a coating of Fluid Film to the underside of my 2012 truck as part of winter prep. I poured a gallon of Fluid Film into my Wagner Paint Crew Plus sprayer and it made the job super easy. Literally went on in a few minutes and I ended up using pretty much the whole gallon. The cloud from a high pressure airless sprayer is pretty intense under the truck so make sure you wear goggles and a respirator. I was covered head to toe in the cheap throw-away coveralls and head sock. It took longer to clean everything up then to spray on the fluids!

I'm going to go ahead and install the wheel well inserts too, just because it will look better. Those are easy to remove to do another application of Fluid Film next year. Maybe I'll beat this damn Illinois rust for once!

 

I live on the ocean, and in New England, so I've actually got an appointment on Friday to have the dealer install a set on my truck. I know they're probably easy enough to put on myself, but this way I get them covered by my warranty, so it's a win-win as far as I'm concerned.

 

growing up in Maine, I've concluded that rust prevention is a never ending battle. Drop your guard and it's back. Sounds like you did a very nice job.

 

I would be interested to see how much salt, etc, gets back behind the liners over the course of the winter. I wish I knew someone nearby who had them so I could see them first hand. Oh well, I may end up being my own guinea pig.

 

I know this thread died awhile back, but I'm debating adding these and wondering how they worked for those of you in areas of snow.

 

They are not the end all be all but they do reduce snow and ice build up in the wheel well. Remember the salty mist will still get all over since the rest of the underbody is wide open- I spray above and behind my liners with Fluid Film.

 

Good to know. I am considering not adding wheel liners or mud flaps just because of the snow build up.

 

I had worse snow/ice build up on my F250 without liners in the rear than I do on the F150 with liners.

Not sure about mud flaps, might be helpful on my f150. I get a big nasty chunk of frozen ice/snow packed up along the front of the runner board which will get bad enough to rub on the door if I don't chip it out.

 

I find that running board piece kicks off easy enough. If it was between the flap on tire, might crack flap or be harder to get out.

 

Husky wheel liners and mud flaps here..no concern with snow build up. i park in the garage so any snow it gets during the day will melt off at night.

 

I installed a set of liners into my super duty three years ago, they do a great job of keeping mud sand and snow off the metal leaf springs etc. I wish i would have done it years earlier because even with extreme maintenance and fluid film spraying etc my drivers side wheel well lip just popped a #2 pencil eraser sized bubble two days ago, since winter is here im gonna let it go till spring and replace the bed side.......
