    Just noticed the lack of paint on all the frame welds. Has anyone else noticed this? Truck only has 230 miles!

    Just sprayed fluid film on all visible welds until the weather improves.

    Just imagine the rust between the sandwiched layers of the frame...

    When my truck was brand new I crawled under and sprayed any exposed areas with black paint before it had any chance to corrode.

    Thanks Guys. I guess my initial question was more along the lines of WTF? The truck is brand new, I don't think there should be any exposed steel at this early stage of ownership. Oh well, up and on! Cheers

    My Tacoma had the same rust when new. I sprayed all the rust spots that I could find with this stuff as soon as possible.

    I’ve also used it on other trucks when new. My last full size truck had the same after bringing it home. All makes start rusting at various locations when new, at exhaust hangers, muffler seams, driveline nuts and bolts, suspension parts and joints, frame, brake parts, hubs, etc.

    I get under the vehicle every year or two and spray away at the spots.

    If you want a small project, take off your wheels and cover up the rust on your rear brake drums and front wheel mating surfaces also. The rust behind your wheels on the drums and hubs only worsens over time and can sometimes run out and stain the inside surfaces of your wheels after a long while.

    I guess I need to lower my expectations from Toyota. I'm keeping the truck, this time!

    Due to the fact the active corrosion is contained to the weld area, it is either from a lack of surface profile (roughness) on the weld, or weld flux that remained on the weld and was then painted over.
    Clean the active corrosion with a stiff wire brush. Sand back 1/2 inch onto the sound, intact paint, and clean with a suitable solvent. (Xylene, M.A.K., etc) Apply some good ole Krylon to the prepped areas in 2 to 3 light coats, allowing 15 to 20 min in between applications.

    One more thing, before you paint, clean the Fluid-Film off with the solvent prior to wire brushing.

    My truck isn't even a week old but I've seen a few of these kind of threads. Guess what I'll be doing on the next dry, warm day! A $7 can of paint and crawling on the ground is well worth the piece of mind and rust prevention!

    That looks like a bronze type of alloy weld... not rust.

    Thanks mate! You just maybe right. I have only seen bronze welding on bike frames.
    Just trying to keep on top of rust prevention. Thanks again.

    Mig weld wire has silica in it. It turns to molten glass & rises to the surface of the weld as the puddle cools. The e-coat covers the silica, but vehicle vibration or impact from road debris shatters the silica crust leaving bare metal to oxidize. I work for a tier 1 automotive chassis parts supplier. We produce welded, e-coated front & rear sub frames for Honda, Toyota, GM. FCA, & Tesla. All of these products exhibit the same corrosion on the welds. Our competitors products do the same. We have in-house cyclical corrosion testing equipment. The corrosion on top of the weld is not the weak point. The weak point for chassis corrosion is the heat affected zone on the metal beside the weld. Particularly on the inside of any tubular part. All manufacturers are working towards improving their corrosion resistance on the "heat affected zone" through the paint pre-treatment process.

    Long story short, OPs truck is FUBAR'd and he should seek immediate legal action to get a FULL refund plus another truck that is has come from an oxygen free environment.
