That's even too much current I think.
Electricity flows like water. If it doesn't have a path to get back to where it came from, it will sit. So yeah, the body is grounded and electricity does run through it, but that's why I mentioned tail gates on trucks. There's no ground strap tied to the tail gate of a truck. Any connection the tail gate has to the rest of the body is painted. There's no reason for electricity to "flow" through the tail gate. It will always take the path of least resistance. If we get real technical, there's electro-magnetic energy in the air. Drive by a set of power lines and you're sure to pick up some electric energy. Plus look at California cars. Super clean and have had just as much electricity running through them their whole lives.
I'm not denying that electricity can increase or speed up corrosion, but I don't think electricity is to blame for the giant rust hole in my left rear quarter panel.

The more I think about it, I think just fastening it to your car isn't going to do anything unless you drive the car in the salt. If you look at California cars again, you see cars that are exposed to rain water, but no salt.
If you really want to simulate "rust belt" conditions, splash salt water on it a few times a week and just let it dry, never washing it.

I would bet that's the root of the problem. Salt melts the snow and turns it to water/slush. The water splashes up onto the body from the tires and cars driving in front of you, and finds it's way into all the little crevices you would imagine and then just sits there, eventually eating through the paint and corroding the metal from the inside out.

salt water. sounds like a plan. I still kinda liked the idea of bolting it to the bottom of my car lol. But then you'd get rock chips and such.

real cars get rock chips and such, which is where they usually where they start rusting.

I have another conclusion. And yes I need to do a picture update soon. I think nothing is rusting because the surface is smooth/flat. Most of the time you paint stuff on cars, it's the uneven surfaces and scratches that rust. EG my welds on the peerless skid plate are rusting ONLY at the spots I welded. I think I should redo the experiment with a weld bead all the way down the metal.

The weld bead is a different material composition which is more porous than the sheet steel OEMs use on unibodies. If you really cleaned up the welds and primed/painted them they wouldn't rust. Maybe try shooting it with a BB gun, scratching it with a nail, etc...you need to replicate the environment the car actually sees. The spots on cars that most commonly rust hold moisture, so try and simulate that.

But there are tons of welds on cars. that's where they rust. I don't think it's the composition, I think it's the texture that the paint can't adhere to. Because I sanded mine down, it had a great tooth to get on. I think scratching invalidates it. Of course if you chip off paint, it'll rust. But this way is TOO ideal. Even the clear coat isn't rusting. Even the clear coat with the sharpie and my finger prints isn't rusting. Ironically, my finger print area has "surface" rust on the metal but it stopped due to the clear coat over top.

I've done metal buildings and welded most every one of them and ones that have been standing for decades in the elements (non enclosed of course) still haven't rusted. It depends on the paint I would say.

I should take pictures but nothing is really rusting. I think I'm going to redo the project again but with a welded bead all the way down. Probably do it this winter.

I try not to get struck by any kind of penis, rusty or not.
