    I have a 2003 Tundra that is starting to get some rust on the frame. That may not be big problem to take care of, but what I am worried about is what may be inside the frame rails. No way to get something inside the rails and clean it out. Is there something that I fan spray in there that will neutralize anything that is in there.

    You could try something like fluid film to coat it all. I think it would arrest any further rust, but I don't know for sure.

    Fluid Film is good. Look up WoolWax too. I believe same company, different smell and a little thicker.

    I use Fluid Film on my frames. My 16 year
    Old Jeep has almost no frame rust ( I didn’t do it from new ) there are several kits you can buy and videos on YouTube about applying it inside of frame rails. Great stuff. Fluid Film and Wool Wax are both just lanolin. Somehow they got the color and smell out of the Woolwax. Haven’t used it much yet compared to the Fluid Film

    Woolwax is better but more difficult to apply. Fluid Film is easy to spray on, but needs to be reapplied occasionally

    Thanks all...I am familiar with Eastwood products, but never heard of fluid film, or wool wax. Gonna check out both of those.
    Thanks again.

    I know it might be tough to get into all the nooks and crannies inside the rails, but i would try to get a good rust neutralizer inside there before coating it with something like a fluid film. Adding a coating over existing rust might just add to the rusting problem. Just my 2 cents of course, and good luck. :thumbsup:

    Fluid film isn't a coating like the black tar mess they use to prevent rust. It's similar to smearing it with oil, so it will soak into any existing rust and (hopefully) arrest the process.

    I do intend to get get some type neutralizer in the rails. I think Eastwood has some with an application gun and hoses. I was and am worried about getting some sort of mechanical device, ie...a wire brush, or whip in there to break loose anything that may be in there. I plan too run a plumbers type bore scope in there to take a look at what is in there, if anything . It may be a moot issue.

    Knowing is half the battle, as they say. Being able to see it will give you intel on how best to move forward.

    I just did mine yesterday with Woolwax. Also bought the kit that came with the undercoating gun. Also had a flexible hose you can attach that sprays in 360 degree directions. Great to get in the closed frame areas.
    For my Tundra 8 ft bed used 3 1/2 bottles. Putting it on pretty thick
    To spray good thru the gun. I needed to raise the psi to 90 -100. And product was still to thick. Had to heat the product to 80 degrees to make it a little thinner.
    Just sat the bottles in a bucket of hot water for 30 minutes.

    3 years ago did my rust areas with rust converter and rustoleum undercoating over that. That was a complete waste of time and money.
    Lasted well on places with no rust. With rust I did a lot of prep and only lasted a year or two.
    May work if you have no rust or very, very little rust.

    I choose woolwax after a lot of research. And think this is the best solution. But not like I have a lot off experience with this and time will tell.

    Everyone has their favorite product to use in this arena, but we all have the same goal of keeping our Tundras rust free!..Good luck with it. :)

    Luckily we have pretty good access to the boxed portion of the frame on our trucks since it's not boxed for the rear-most 2/3.

    If you haven't already, check out the pics in this recent thread. They give you a good indication of the problem areas you should pay particular attention to when you're inspecting with your boroscope.

    As others have suggested, fluid film is a good choice and is mentioned each week when a tundra frame thread is started.

    If you won't more reading and comments, the below forum search shows most of the past weekly threads concerning frame rust....

    Having a 1st Gen I’ve been using a two prong approach:

    1) Grease rubbing the entirety of frame with Moly-b even using a plunger to get the grease up into the boxed portion under/around the engine. The grease over time turns into a gooey shell that doesn’t wash off like Fluid Film.

    2) PB Blaster Penetration Spray shot up into the box frame to get into all the nooks and crannies/welds. You can slide the little straw into the factory holes and spray. Also, you can direct some spray between the frame overlap at said holes. Open the engine hood and soak your frame from above directing into the holes as best as possible. I’ve done this a few times in the past 2 years with success. Stay vigilant.

    Throughly pressure wash then fluid film spring and fall. Keep it up every year you will be good.
