Anyone Fluid-Film Their Frame Yet?

[XYZ]

I was thinking of doing this before the truck gets a lot of road time, but the factory undercoating is pretty fragile; so haven't pulled the trigger yet.....

Actually, some of those products will cause the factory stuff to come off faster.

I plan on treating my frame with FF in the next couple of weeks. Never had an issue with it, if there's issues with using it someone please post a link.

Most of the rust issues with frame rust people are screaming about will never effect the life of the truck. Ive had more than my share of old cars and trucks, none of them had treated frames unless I did it for looks. My latest lowered 22 year old truck is bare out side of a little surface rust is just fine. My new truck if I can see it a little rubberized undercoating fixes it. Im not going to look under the truck for a spot of surface rust that will never rust through the frame. The leased amount of time my truck spends at the dealer the better.

The Fluid Film will soften the factory wax coating. I use it on the painted underbody surfaces, but not the frame.

I know of a few that live up north have used AMSOIL's HD Metal Protector on the underside of their vehicles with good results.

I just FF'd mine a few weeks ago. It does soften the factory undercoating but it's still worth putting the Fluid Film on. Once there's a flake/crack/scrape in the factory uc, it seems to accelerate rusting of the frame if anything. Fluid film is one of the few good options out there. Krown is supposed to be good if you're in Canada. Krown and FF are supposedly pretty similar.

I do absolutely nothing to the frame of my trucks. Never had a problem, just one more reason I love living in the south.

I do nothing as well, and I live in the world of salted roads.

2016 Silverado + Fluid Film application about a month ago + a few car washes + a few days of salted snowy roads. It definitely softens the factory 2016 undercoating. I am going to apply in those spots again.

The factory wax coating only seems to get a winter or two before it starts falling off anyway. Who cares that an undercoat softens it. It least theres less time that the frame is exposed to the elements that way.

if you're that worried about the wax coating, I'd just reapply it. You can buy a can of that stuff. The exact name is listed in several threads. I think its like nox-rust. If you are under bumper to bumber warranty, i'd see if the dealer will repair it for you. I got mine to reapply it right before my 36 month mark.

 

I use fluid film every year on my snow plow, but I only spray it on the steel parts. The directions specifically say to be careful applying to other surfaces and it is known that it can damage rubber.

I live in MA & my truck gets pummeled w/ road salt/sand etc. all winter. I make a point to re-apply the factory wax coating once yearly smack dab in the middle of SUMMER when its hot & dry so the coating adheres well & also so there's no chance for trapped moisture causing rust beneath the surface later. 

 

Depending on the condition 1 or 2 cans does the trick, this year I went heavy & did a full 2 spray cans of it everywhere underneath & it seems like reapplying helps the wax adhere to parts better & keeps it supple w/ way less flaking occurring in between applications  - I have 58k miles on this truck, previously my '14 had 45k miles on it before I totaled it and DIDNT treat the frame - its fairly obvious the frame/undercarriage on my current truck is holding up MUCH better.

 

My truck is leveled I don't even really need to lift it up to get a good application (although I do drive it up on ramps to really get a good look underneath) - safety glasses, respirator/handkerchief, a creeper & 1-2 $20 bottles of nox-rust all you need.

When I bought my truck in Apr 2015 I was warned about using FF as it would void my warranty... SMH who cares about my frame warranty when the fix from the dealership is to just spray nox-rust over the existing rust. I have fluid filmed my truck in the summer and late fall every year since and touch up bare spots with Nox-Rust. It does soften the wax. I will not deny this. But the wax was already soft thin and crappy from the factory. The high "spray" areas are prone to wearing the ft away and I will touch these up a few times in the winter. Overall if you look at my frame and park it next to any other 2015 in new hampshire you will see a shiny greasy soft wax coated frame on my truck, and a rusted nasty looking frame on another. I suppose it's a good thing that driver protected there factory warranty.

I bought the 5 gallon bucket of fluid film and the kelsport spray gun. I undercoat all my winter vehicles (4) every year and I usually get two years out of a 5 gallon bucket. Stuff smells like dirty scrotum, but my frame has no rust!!! My braklines have not rust. I plan on having my truck for atleast 10 more years. Long after the warranty will dry up. I also pressure wash my vehicles at minimum bi-weekly even in the deep winter. I have had no issue with the water damaging the frame wax with ff.
