Hey, anybody that is using Fluid Film, do I need to do anything special to the underside of my rig before I coat it with Fluid Film for the winter (Other than a good wash with the pressure spayer) ?

Thanks,
Brian
 
probably not just scrape ,brush Power wash clean and apply fluid film when undercarriage is dry , and warm if you have a heated garage??Get it in bottom of doors ,in tubular x members ,any place rust is or can start
 
I just did mine, I just brushed some of the leaves off. If I power washed it - A) it would never dry until next summer, and B) it would take all the previous antirust treatments off.

But yeah, if it was covered mud, I'd give it a good wash. (My favorite is to hook the power washer up to the hot tap and make it look like a volcanic steam vent has opened up in the street in front of the house..)

I applied the Fluid film this year with an old electric paint sprayer. Worked fantastic. I tried to use a undercoating gun with my compressor last year but made a mess 'cause the air atomized the Fluid film and spread it all over the place and only put it thinly where I was aiming it.

The only issue I am having is getting it into the frame rails. Usually I have a Krown treatment done, which does the frame nicely cause the oil is much thinner and they have those nice wands, but I missed getting it done and they don't do it once the temperature goes to freezing.

So how are you planning on getting the fluid film inside your frame?
 
Hey Joe,
I read someone else's advice about inside the doors, has anybody had problems with it causing the drain holes getting plugged over time? Doesn't Dirt and other crap stick to it over time?

And I only wish I had a heated garage- hell, I wish I had a garage. For half of the $ it would cost to build a garage in DC (inside the city) I could just go buy another rig every year for the next 20 years instead- not to mention having one heck of a parts collection :) - oh wait then I wouldn't have garage to store the parts in- damn it is a catch 22!

Thanks for the advice about the cross members and such.

I haven't bought the stuff yet, but if it will flow through a paint sprayer, I am thinking one of those cheap gallon size chemical pump sprayers from HD with a wand- then pump the thing till my arm falls off I am sure

I will let you know how it works out.

I brush painted the insides of my doors. I put it on thinly enough so it wouldn't slump to the bottom of the doors and fill the holes. I also cleaned the munge out of the door bottoms before I started. Dust and stuff will stick to the FF but not alot of it gets inside a door that is in good shape.

One note. Fluid film is really quite thick. I had to thin it with engine oil to make it work, and those electric sprayers are a lot more powerful than the cheap gallon sprayers. Last year when I tried, I couldn't get FF to suck through a spray wand intake hose with a compressor at 90 psi.

Anyway, keep us informed of what you find out!

I bought the gallon can of FF for spraying the main areas. I also grabbed a few of the aerosol cans with the straw for shooting it into the frame rails, inside quarters, and any other nook and cranny I can find that can use a coating.

freewheel, I don't doubt you- you have actually used the stuff, but if you couldn't get it through an intake hose with 90 psi, how do they get it to spray through one of those "Windex" style trigger bottles that they sell on their website?

or am I going to get some surprise instructions that tell me that I am going to have to thin it down 5x or something?

oh well, we shall see next week, I ordered it anyway-

I've done it twice. Pressure wash the hell out of the underside of the truck, and in all the little access holes in the frame rails. Let it dry then go at it with the FF. First time I did it I used a garden sprayer with it thinned down (mineral spirits?) and brushed it around to get an even coat on the outside of the frame rails. This fall I used an undercoating gun, again thinned a bit with mineral spirits.
 
Windex bottle on steroids? ;)

The Gallon can of Fluid Film NAS has a consistency similar to Jello pudding. Great for adhering to vertical surfaces. Less fantastic for spraying or sucking through a feed tube. Though maybe it was the fault of the $12 spray wand on sale for $7
:D


Or maybe they have a different formulation that they sell with the hand sprayer.
 
I've found it at John Deere dealerships. Lots of them seem to carry it.

As far as applying it, if you can, jack the front end up as much as possible and spray out the inside of the rails till all the mud and gravel comes out and the water runs clear. Then once it dries, you can get pretty good inside coverage from the aerosol cans with the red wand attached. The stuff creeps really well once it gets warm.

Which is a good reason to apply it before it gets cold outside. Or in a heated garage.

http://www.napaonlinecanada.com/UAP/upload/news/fichier/15424_UAP_36p_An.pdf go to Page 17, bottom left corner is more reflective of the gun I have. I got mine through Lordco Body Shop Division though. It came with two wands. One is perfect for getting into frame rails. It's has a 180deg spiral head via a slit which goes all the way around the end. I spray fluid film with it, however do make a witches brew to thin it out (using either Boeshield, 3M Rustproofing, or Proform permanent wax based product).

Fluid film does displace moisture. Try it into a seam you know has moisture, and what the water start dripping out.

Yes to John Deere in Canada as well. By the spray can, or by the gallon (last time I checked).

+1 on John Deere shops. That's where I pick it up. The local Deere shop here always has the aerosol cans in stock, and occasionally has the gallon cans. If I order 4 gallon cans they can get it for about $34 dollars ea. I don't need four gallons but the next time I buy I'm going to see if I can get some friends to go in with me on it. I always keep one or two of the aerosol cans handy.
