That's interesting! Maybe once the winter clears I'll actually get under there a do something similar. Some guys at work mentioned POR15. Id like to go that route because it really seals in everything.

I use Krown (Rust Proofing Protection on Cars, Trucks & Vans | Krown Rust Control) they drill holes in various panels as well and spray their "oil" into/onto everything.. its messy for a while but does better than any other treatment I have used or heard of in Southern Ontario (Canada's rust belt) ... however -- while it is the "best" ... it does not eliminate rust ... it just slows it down. IF you drive in the winter here ... rust is a fact not an option. It's not just the salt ... it is also the cold dampness that never lets a vehicle completely dry in the winter months here.
The winters in Southern Ontario are pretty much identical to the area I live now and used to be at in Michigan, personally I'll take PM Industries "Master Series/Master Coat" products over anything offered by Krown.
Vehicle will be up on a lift in a week or so, I'll take some photo's of the undercarriage and post them to this thread.

Blew through 4 gallons of fluid film last Sunday, did all my vehicles, my father in laws and my neighbors. I buy in bulk and have the spray gun to hook to the compressor.
I do it in the fall but will do it in the spring this year as well. I sprayed more heavily this year and it really looks great.
Best stuff I have found, easy to use, cheap and safe. Funny smell that some folks like and others seem to hate.

X 2 . I do it every fall to my winter vehicles. 5gal pail, gun, compressor, lift and a face mask! Does smell like sheep.
Looking forward to see the pictures of your undercarriage as I'm also looking for a low maintenance rust undercarriage protection.
What do you guys do to frames that already have rust on them? I have one friend who bought an old jeep that had quite a bit of rust underneath. He took a wire wheel to most of it and then sprayed a couple chemicals on the whole underside. Looked great when he was done but not sure if the rust came back as he sold the jeep about a year later.
I removed the cargo carpet from the 80 and there is some rust forming on the floor over the rear tire...what would you guys do to remedy that?

Does fluid film leave a thick residue or would it be gone in a year or two? I never see snow where I live but might spend one winter in Maine soon. I want to protect it but I don't want it complete my hopped up for years to come.
fluid film will wear off in a year. If you want to remove it you can spray it with soapy water and it will come off with some pressure.
You can vary the thickness on how you spray it as well.
Good luck

one thing to remember is on to get the crap off the upper shock mounts as they hold dirt and rust against the frame. Once clear, take two handfuls of fluid film and just smear the crap out of each side. I just applied 2 gallons of fluid film to mine.....
Also, fluid film is only really needed for rusty frames.....no rust use AMSoil HD Metal protect.
I use the spray cans on all types of random s*** I don't want rust appearing on.
Not true, i'd use fluidfilm on a new vehicle in a heartbeat to prevent rust over that amsoil crap.
Once I get the rust wired off in the next few weeks I'm going to coat with Chassis saver then once that is done coat the entire underside with heated mineral sperits paraffin wax and 30 wt non ditergent oil mixture or chain oil.
Same here. Storage once the first salt flies. Then removed april/ may depending on the winter. I still use fluidfilm though.
I just spray my junk twice per year. Over time, the FF seeks bare metal and you can scrub, wire wheel and power wash off the rusty "mud" that builds up. Once things are pretty far along though, the steel itself gets eaten away and you will have less rust, but the parts are still compromised. As long as you don't have holes or places that have rusted all the way through and are like sedimentary layers, the FF will keep things from getting worse.
I would sand the wheel well down to bare metal and then hit it with some Rust Reformer, then rusty metal primer and then finally top coat with a layer of matching paint and then clear coat. Let it cure over night in a warm, dry area and then put the carpet back. I would also be spraying the wheel wells religiously with the FF each fall and spring and be washing the truck once per week in the winter if you live in the Rust Belt.
It is grease. Like a stick of butter it can be vicious and creep into crevices and it is also quite solid when cold. This is why it is best to apply when it's warm out (80°+ out). Mud won't really stick to it but sand readily will. It is very nice that you can stick the tip of your spray gun in the many holes in the frame and even do the inside. Wrap newspaper loosely around exhaust system. Wear junk clothes when spraying.
Oxidizing or rust of steel is caused by oxygen reacting with iron. Grease or any other coating prevents the oxygen from getting to the metal. The more expensive coating have great durability, but you MUST have clean metal to begin with or the rust bubbles underneath and moisture and air are trapped next to the metal making the rust worse than if you had done nothing. When replacing parts coating will have to be burned off and redone. With FluidFilm replacing the film is as easy as filling a tire. I have the spray bottle full on shelf, hook up air and go.
