    So, I haven’t even had the chance to tow anything yet, and put an armored step in the hitch receiver since that’s useful to me — and today noticed that at 6000 miles with this thing mostly garaged, some of the black paint had peeled back at and around the receiver’s opening and it had started to rust at the edges.

    Is this just a lifetime battle with the hitch receiver? When I bought my old Ford Ranger, year’s back I just accepted the nonstructural rusty bits (like the tow ball) as “character”. Not so much on the new Runner.

    I noticed the same thing within the same number of miles, always garaged and hitch not yet used. There were a couple pieces of paint that flaked and fell off. I haven't done anything about it, buts curious what you'll find out.

    I had some paint flake off my never used hitch too.

    I cleaned it up and touched up with Krylon when nobody was looking. ;)

    Clean it & use Rustolem, that $hit is great. It's the fish oil!

    Get a Small Can of Black POR-15 clean the entire receiver real good then coat it with the POR-15 you just take a small 1/2 inch paint brush and apply it and be done with it.

    Thanks, all. Just wondering. Figured I would hit it with some Rustoleum, but just wanted a quick gut check.

    I see you're in New York.

    It's not going to be a lifetime battle with the hitch, it's going to be a lifetime battle for the whole truck, lol. Any metal exposed to humidity or road salt is going to rust. (on any vehicle really, but BOF Toyotas seem especially prone to it).

    I highly recommend you get the undercarriage Fluid Filmed (or similar) before winter hits. It's going to take some vigilance on your part to make sure it stays relatively rust free.

    Agreed but Made in Japan never had the crappy frames like Taco. You want that fluid film done by a pro to first descale it and second make sure that the inside of the frame is sprayed thick. Fluid film is great because of the way it creeps and clings. It is not expensive.

    A friend of mine suggested spraying fluid film on a wax applicator pad and putting on tow hitch, I also plan to do that on the bracket where the trailer wires go in.

    I need to find someone good to do fluid film. My dealers said to watch the the rubber seals though as they will expand. They recommended Ziebart which does not seem like good idea.

    Crazy...trying to find someone to trust who knows how to spray this (at least in Michigan the rustbelt for sure)

    Spraying isnt hard, it’s just a royal mess if you are going to be thorough. I got a cheap airless sprayer from harbor freight and a gallon of wool wax. I also got 4 cans with the wand to get inside of frame. Very messy. The airless paint sprayer worked ok, but was easy to over spray or under spray. Not very precise

    If I had to do it again, Id consider brushing the bulk product on, and using cans and wand to do inside of frame

    No need to be all fancy with the fluid film, no need to use any wax applicator pads or anything. Just spray it directly on the hitch, it'll even itself out.

    I had mine sprayed before the winter at an off-road shop, a hundred bucks to do the undercarriage. They spray it from a spray gun and have a couple different wands that they used to get up around and inside the frame. Definitely worth it, considering a case of six spray cans is about 50 bucks.

    I would find a new dealer. Fluid film is lanolin based and does not attack any rubber seals or gaskets or lines, also Ziebart is complete trash. It looks nice on the outside, Meanwhile your frame is rotting from the inside out. Here's a little video that perfectly illustrates that:

    Any body on frame Toyota got the crappy frames. If you live in a road salt area, it's going to happen. Look at 100-series Land Cruisers, those are made in Japan and those will rot out. Same with the 3rd and 4th gen 4Runner. I stopped looking for a 3rd gen in New England because all the frames looked like they came up off the Titanic.
