Fluid Film long term problems for undercoating

[waterman]

Hello,

The thought of winter is driving me crazy knowing what it can do to my cars. I am planning on using fluid film for the undercoating on my cars, neither has any sign of rust. I was curious to know if anyone has used this and has any problems with it. Has anyone used something else that has worked?

Thanks

There are lots of guys over at TacomaWorld that use FF with no problems

Not sure we're your located but Krown or Rust Check are great products. I am in Southern Ontario but the amount of salt, sand and brine they use on the iced roads in the winter will make a clean car cry.

I live in NH, where our winters can be a bit rough. Honestly, my 9 year old DD didn't have an ounce of rust. As a matter of fact I recently had the car on a lift, and the mechanic stated the undercarriage looked like a new car. My wife had a Honda Civic for 13 years, not one touch of rust.

I accredit it to two things, cars are made better today (unlike the 60's, 70's and 80's... 70's being the worst) and taking them through a touch-less that gives a good undercarriage weekly has attributed. After the Touchless gets the majority off, I give the car a full rinse-less wash and a good QD wipe-down.

I can't give you a definitive answer, but I've been playing around with Fluid Film a bit since I found it in spray cans at my local Lowes. I do believe it stops rust, based on a couple test areas I've tried on my DD. It must actually dissolve some of the rust, since wiping off the excess leaves rust stains on your rag. My only concerns are: 1)It never fully dries, so it's a dust collector. 2) It may make it difficult to prep a FF-treated surface if you want to do a permanent coating later, such as POR-15. 3) I don't know how well it will stand up to constant water/snow/ice blasting when used on the underside. Last spring I did a few areas under mu daughter's Honda, so I'll inspect it soon when I do my winter oil change. I'll do a few more areas, take some pics and keep notes, so I can compare in the spring.

BTW,I've been using it also as a battery terminal protectant and it does a fine job there.

I used a can of fluid film last night and was only able to do the back of my truck (Yukon Denali). It does have a strange smell to it and definitely bubbles. I may have sprayed to much on.I tried to get everywhere I sprayed with a rag to smooth things out. I'm not really worried if I can see bubbles, I just want it protected. I am concerned about dust and dirt collecting.

Sorry, I forgot to mention the smell.
IIRC, this stuff is lanolin-based, derived from sheep. I've never been to a sheep farm, but if that's what they smell like, I won't be visiting one soon. The smell does dissipate in a few days.

I use it on my trucks and it does a great job. It works best on cavities and will wear off if put on like front end parts. Collects dust. I recomend it.

ebay for 77 bucks shipped you can get 1 gallon of fluid film and a fluid film brand sprayer
