Frame Rust treatments

Looking to treat 02 Tacoma with a fairly new frame.

I am debating going for the Fluid Film NAS treatment, DIY using a kit, or using a 50% mix of used engine oil and used transmission fluid, sprayed on.

Any thoughts?

 

Fluid film is a very good product for this. Smells like shit but it works! You must coat the frame both INSIDE and OUT and do it every year to keep maximum protection against rust

if you want to use spray cans, use this 360 spray wand to do the inside of the frame:

5 years now and still looks new Fluid Film is awesome.

 

Fluid Film. I know Ford uses the "motor oil and transmission fluid" as a factory solution, but Tacoma engine and transmission does not leak that much to create a rust-proof protection.

 

interesting would somebody from like Florida would need to do this ?

 

I don't know about Florida, but driving my truck in California for 18 years I have never heard about Fluid Film, and the frame was pristine like from the factory.

 

oh, florida? no, you don't need that. You don,t have winter salt and chemicals where you are. You are safe.
The only exception would be if you drive on the beach and saltwater and park the truck in a pond. Saltwater is as worse as winter salt

 

Fluid film is good. Been using it on my 2004 since I bought it to MA from South Carolina 4 years ago. Frame has held up well considering the extent of salt and other crap used in MA. Really want to protect it? Paint all the welds with rust bullet and paint the inside of the frame and bumpers with eastwood internal phosphate frame coating. (green but now I think it comes in black) then spray the crap out if it each fall. (after power wash each spring.)

 

Looks great, did you do this or did you have it done? I am still looking for someone to do it for me. I would not know what to spray under the truck. Plus at 70, me crawling under the truck is not a option

 

We have a Fluid Film party yearly and for $50.00 your good to go

 

I was wondering about the Eastwood product. I tried POR15 once or twice and it bubbled up again within a year. Rustbullet seems similar. Using their (Eastwood) rust treatment then just Rustoleum black over the outside strikes me as good enough to start.

Those heavy paints and heavy undercoating deals just seem like they cover the rust really well, but do not seem to be able to penetrate it and stop it. When I was looking for a truck, a lot of people gave me that "I just undercoated it" line. I was polite as possible while backing away in a hurry. Hides a lot of sins.

That's why I am leaning to something like the Fluid Film or the oil treatment. Do not appear to cover up anything and seem to penetrate the rust really well. The oils seem to have additives, especially the trans fluid, that have anti corrosion properties.

 

I'm going on 73 and figure I can crawl under there for a couple more years. Maybe not get up as quick as I did once . . .

 

Fluid Film does not "coat" as a paint, but creates a layer that is a little bit sticky (like a wet rust oleum paint) then the dust will cover the sticky surface without soaking it (like oil would do). Here is the picture of the frame (the sensitive part) 11 months after applying fluid film last year:



The same area after fluid film was washed out (pressure washer with hot water and soap) before applying again for the next season.

 

I get a dripless oil spray from Napa which comes in a 20 litre or 5 gallon pail in either gold or black and usually on sale for around $85 Cdn. in the fall when most people undercoat their vehicles in Canada. I have a cheap spray nozzle (Harbor Freight or Princess Auto) which has a nipple at the end and I attach a rubber hose which in turn goes into a 1 gallon old container ( engine oil jug) of this product. One pail of this does both vehicles for about 5 years or so depending how much product you use. I only have a small compressor which works fine but you probably should give it a rest once in a while. The amount of oil you spray can be controlled by the control on the compressor but I seem to use around 50 PSI. Fluid Film is a great product but very expensive if you use aerosol cans and this way is a lot cheaper and works very well. Another great thing about the Napa dripless oil spray is that if your vehicle is rusty underneath, you can mix it with ATF or hydraulic oil to thin it out to give it creep value and soak into the rusty areas. I never drill holes like Krown or other companies do as I spray into the drain holes or other plug holes of the doors, hood, tailgates etc. and most vehicles have plugs under the doors sills. Nice thing about this is you see the oil mist coming out of the other end of where you are spraying so you know you are getting good coverage. Hope this helps

 

Is that the rattle can Fluid Film or the NAS version? I've used the rattle can version on a tractor that sits outside. Seems it will wash off after a bit.

I did get your dig at Ford, but, the 50/50 mix of used motor oil and used trans fluid was a serious suggestion, given to me by an old hand at Jeep CJ's. Claims it worked better than any commercial solution. Cheap AND Dirty for sure.

 

Seems to be a Napa Canada only item. Price shown for 5 gallons is over $500.

 

I just called Napa - black color is $98 out of stock till fall 2019 but gold is still available at many stores for $91 cdn or about $55 US. I am sure you could get it at a northern state where salt is an issue.

 

LOL I can't believe this comment didn't get more love

 

at nearly 50 my neck and back are so stiff I know exactly what you mean
i gotta shell out BIG Bucks to have this done (current estimates from 850 to 1500 for a local shop(s)) and no clue if they are even
going to get the job done right so as to ease my worries
I wish I had a lift in the garage so I could stand underneath but garage is not big enough!

 

what's the name of this dripless oil from napa you are using? I'm interested

Also, yes, fluid film spray cans are very expensive but I found another product that works just as good and is cheaper: Honey Goo. It's only sold in spray cans but a can is less expensive than a can of fluid film
