Depending on your environment applying stuff like that every year or two can help some. It isn't a magic pill but products like that can help against rust where they are applied (you won't get everywhere). I sprayed down my truck with PB Blaster Surface Shield (similar product). Stuff under there is a lil greasy feeling if you're working on it later and if you get some on heat shields/exhaust that will burn off initially.

I think it’s great. I live in the rust belt. I apply it heavily before every winter. I do it myself. Both of my cars have very little rust underneath. I’ve been doing it for years. I can try to answer questions.

I own three vehicles, and all three are undercoated with FF. It needs reapplied/touch-up every year, but does a good job. The only thing I don't like about it is, it seems to attract everything and whatever is attracted to it sticks. Has anyone else had this problem?

That was going to be my comment about it. I put it on a couple years ago and it grabbed all the dust pretty quick then seemed to wash off not long after.

The fluid film or dust washes off?
I’ve never really looked that closely at what sticks to it when I’m done.
With a new vehicle I load it on and then the following years I can typically put on less because it’s still covered. I coat a buddies truck yearly and he takes he to a car wash with an under body spray almost weekly during the winter. He washes most of the ff off, and his truck has a lot more rust than mine. He asked me again to put extra under it again this year.

The fluid film washed off. I do go to an underbody car wash and that doesn’t help

Underbody car washes are definitely bad for FF coatings.
I don’t rinse the underbody until the spring and I use a garden hose. The only places that rub off on mine is bottom frame and anything low hanging. Usually from driving through fields in tall grass.

Roger that,I drive on the beach all the time and anticipate sand sticking but it seems better than having the truck rust out completely,least it will seal the salt out

Local shop said they would do my pickup for 500,I'll do that before I head down the beach

WD-40 will do the same thing for significantly cheaper.

Go buy a cheap sprayer and ramps from harbor freight. Spraying a truck on ramps goes quick. The first year I spray a truck I put about 2 gallons of FF underneath. Every year after that it’s a gallon. It’s $30 a gallon at Napa, and takes no more than half hour to spray.

I use FF on the boat , bulldozer, tractor, in a saltwater environment, spray it on in every nook and cranny of the machine and then leave it alone/ don’t use any underbody wash till after Easter/ last freeze!
It really soaks into the underbody, I even use it on my leather boots to water proof
Spray it on a plow disk or dozer blade and mud rolles off , same thing with fender wells and rims & tires ( if you’re going on muddy roads or salt water marsh)
I love FF on metal and leather
( the stupid Fing oil companies use salt water wells to fill the water trucks that water the road to keep summer dust from rising, so salt damage is now a year round problem in Texas and New Mexico)
