I actually never heard of it, but I did see some reviews and folks seem to like it. I wonder how long it will last sense it does not dry.

You can try over a Eastwood for more products

Never tried it, but I would. I've seen it advertised on some of the automotive enthusiast sites and it looks like a pretty good product (of course it does, they are trying to sell it!). The biggest complaint I have about GM is that they put that stupid wax coating on the frames of the trucks instead of paint. If you four wheel and/or drive in high weeds in fields it gets stripped off the frame pretty quickly. I hated seeing the ugly surface rust all over the undercarriage of the truck. I cleaned mine up, then used rust converter spray paint. I had a couple of cans of spray bedliner that I was going to use but never got it done as I traded the Av off in March.

There's an oil spray product for the undercarriage that's very popular in Canada.

I started using Fluid Film about two years ago, and I'm pretty impressed.  I do find that it does eventually wear/wash off, but it seems to do a stellar job.

Every time I change the oil, I spend my time looking over the entire underbelly of the truck, waiting for the oil to completely drain.  At this point, I apply Fluid Film to every stop of rust or bare metal I can find.  As a result of this, the underside is quite clear.

One point I would stress is that you really want to shake that can up well.  If the weather is cool, I will also stick the whole can in warm water for 15 minutes.  If you don't mix it well or if the Dan is cold, you will find the product too thick - it won't flow well.

I'm at the point where I always use Fluid Film during each oil change for my daughter, son and wife.  I use about 1/2 a can per car/truck.

I've been using fluid film for about two years as well.  It will wash off in higher contact areas like where the frame is exposed in the wheel wells.  I apply before winter and then most importantly in the spring after the slush is gone.  The waxy undercoating used on these things is terrible and my Ave had rust on the frame when it was new and the undercoating was peeling off.  I bought the 5 gallon pail of fluid film and a $10 spray gun.  The first two application took a lot but since then it is minimal.  Big thing was to drop the spare and spray up behind it that area was rusty but it is between the two rear tires. 

My 2003 Ave had 160,000 mile on it and was good mechanically and body wise but the frame rusted out.  Hoping to head that off with this thing.

Dusting off an old thread...

I'm starting to get the dreaded bubbles on my passenger rear fender and the bottom back of the rear door area so I've been searching frantically for something to use.  Been seeing Fluid Film a lot.  I stumbled upon this YouTube comparison that provides good, objective testing.  https://www.youtube.com/watch?v=oXlhmbvdKBo (https://www.youtube.com/watch?v=oXlhmbvdKBo).

A member on the E46 Fanatics Forum to which I belong mentioned Corrosion Free - https://corrosionfree.com/product-category/vehicle/ (https://corrosionfree.com/product-category/vehicle/).  I think this is the one from Canada and looks promising.  I think I may give it a whirl.  As much as I have despised the weather this winter (I LOVE snow and we got none) it has proven beneficial to our vehicles since there has been virtually no salt spread on the roads this year.

They have other stuff as well... been in business a long time.

POR-15 is IMO best Paint Over Rust stuff out there.

Surprisingly, the POR-15 didn't hold up very well in the test in the video.

a lot of guys at garage journal swear by FF.  They apply it annually.  I think some buy it in bulk and use like a garden sprayer to apply.  Its a bit messy and IMO its smelly, but its underneath so that doesn't matter much.

didnt watch but did they then topcoat?

POR 15 is basically a primer and needs regular paint on top as all it does it stop rust and form a simple primer surface.

I don't think so.  I don't know which product he used, other than it had to be brushed on.  The thing with fluid film and the similar products is that they don't trap moisture in.  A lot of the products trap in moisture that can lead to more rust.  I'm thinking a POR15 rust convertor followed by a treatment of Corrosion Free.

You are correct about trapping rust under a coating it only makes it worst big time.

When I did my brake lines I use rust reformer on my frame and its holding up well then last summer with my spring shackle replacement I did the rear frame. I thought about using the 2-1 sealer but I decided to wait until I stop the rust.

Like everyone said who know rust better than Rust-oleum. it worked on the hand tools and a cast iron table saw.

On paint bubble there is really no way around it you have to sand the rust out reprime and repaint.

PS zinc primers don't work

Yeah, the bubbles and part behind the cladding on the rear doors are what have me nervous.  I can replace parts but I am no body man.  I'm just hoping to slow it down until I can afford a full rust repair and repaint - probably a couple years away.  Im contemplating a full rebuild of the front end this spring/summer.  I think I'll take your approach with the rust reformer while I'm in there.

There are holes in back entry point of the truck where it must have been hit with a rustproofing treatment.  I'm thinking of popping the helmets off, spraying rust reformer in there and then Corrosion Free once the Rust Reformer cures.

Quick question, do you know if they sell Rust Reformer by the gallon for a spray gun or only the aresol cans?  How much did you go through on your project?

Thanks  :thumbsup:
