This process isn't new. Certainly elder than 20 years.
The paint is dispersed (and not soluted) in pure water (saltless and whatever). The body is dipped into the "paint" and the paint particles are attracted by electrostatic forces. It goes into every corner. It is done for corrosion protection. You can compare it to powder coating if you replace the air with water. The water has the advantage of reaching everywhere and evenly distributing the paint particles opposed to the powder mist with powder coating.
Dipping in thinned paint is really primitive. You can't controll the thickness and coverage.
Then you already have a picture of the uneven distribution and all the drips and tears. :-)
Now, the right name for that process came to my mind "electrophoretic deposition". It was invented 1963. An other name is "Kataphorese". So it ain't electrostatic forces.
I already knew that you are a full blown Nazi asshole. Stunts like this just reinforce that sorry image. Its damn easy to make enemies. Any Dummkopf can make enemies. Making good friends is hard work, but well worth the effort. You don't attempt to educate, you just damn anyone who doesn't kiss your sorry ass.
Herr Obansturmfuerer Muller still posting? I thought he was off in Poland with his Enszatzgruppen gassing Jews?

Yes, my standards for friendship ARE different. All I expect is for them to be friends. Nothing more, nothing less. I used to do contract electronics for several school boards, where they did their best to treat everyone the same. I've had friends that would make even you look like a mental giant. They were classed as mentally retarded, but if you took a little time to teach them a job, they would work hard, all day long and do damn good work. So what if they couldn't drive, and had to live in a group home? They had dignity, and didn't have to feel superior to anyone, like your sorry ass. They knew their limitations, but EARNED a living, by accepting, and working around their limitations. Someone that can't walk because of birth defects? They found something the could do sitting down. They couldn't count above their ten fingers? It didn't matter, when their job was done by the case lot.
That damn inferiority complex of yours is still causing you big problems, isn't it?
So, you don't want friends, you want suckers that you can rip off.
You don't want idiots for friends, yet you can't spell? Bwahahahahahahahahaha! What a "WAIST" Nick, you don't need any idiots for friends, because you'll always have yourself. You are truly a pathetic example of a so called human being.
Oh, yeah.. good ol' Smoluchowski and friends, Vienna and the Copernicus Society of Natural Scientists, alternatives to chromates, biology, and why the sky is blue (seriously), etc.
Post pics of your electrophoresis setup, especially if it cost less than $250 to assemble. There aren't any on the Harbor Freight website. It would pay for itself performing DNA testing, when it's not needed for coating shop projects. I discovered/learned that it is a standard and preferred method in the auto manufacturing industry, just as you said.
The methods of dipping were apparently fairly well studied, I suppose, because the runs and "tears" were very unlikely to be on the side that mattered. It may matter if there are runs in the primer on the underside of a panel for a Bentley or Rolls, but of very little importance on a Detroit production car.
I understand that dipping to apply primers/corrosion inhibitors (specifically not paints), is an old method. I disagree with your statement that the thickness and coverage can't be controlled. I doubt that it was as simple as it sounds, and I speculate that the viscosity of the compounds was fairly closely controlled, and that the vats and/or the parts may have been heated prior to the application, among other controllable variables for different sized and shaped parts.
I've applied coatings to preheated parts, and the results are very positive. I know that many years ago, independent autobody collision and refinishing shops had bench heater units for their paint gun cups, so that the compounds could be heated before application (and these methods were taught in trade schools after WWII), so it would seem very likely to me that heat was used in production environments too (other than just forced drying).
I wouldn't suggest that someone should have high expectations of dipping parts in a can of porch and floor enamel.
I've been lucky enough to have spent time with guys that painted vehicle panels with brushes in factories many years ago, when fenders were pounded into shape on sand bags as a production process. No fancy-boy climate controlled booths, just huge old drafty metal-construction production isles with poor lighting.
Dipping was the old standard for many decades (kinda where my comments started in my first response).
Many of the vehicles I worked on were produced from the 1950s to the '80s, although quite a few were '20s and '30s, when body structural parts were hardwoods. No electrical current dispersed and deposited materials suspended in heavy water (yuk yuk) processes in use, for car bodies back then, I don't think. (had to specify car bodies, or someone might bring up electroplating)

Anyways, thanks for bringing me up to date, even though I'll never use it.
I think we need more zeroes! The point is, if it looks like "oh, they just dip it in paint" from the far, it actually might be more complex.
I don't know how they did it before '63. At least, the runs take longer to dry. You have to turn over and rotate the part while the paint dries. Not very handy with car bodies. Doable and done with smaller parts. But they are rotated while the part dries. I wouldn't like to do that a home. :-)
Me too.
Ah! That is a trick worth noting!
Yea. My point. A roller does a better job.
That reminds me of the early 80's when I watched someone at the production line applying rock guard paint (? is that expression right?) to BWMs. Just a really big brush. And it was in an area (right below the doors) that was visible. Anyhow, he was better than the machine that
Oh! I'm sorry! I didn't know that. I didn't know that those I'm talking about are metally retarded. Look, they can read and write and they share the same hobby metalcrafting. But now it's clear. *That* is the reason for their OTs. It's kind of hard for me to judge that from the far. So I'm asking them to put something like "I'm mentally retarded" into their signature, and I'll treat them with respect.
Yes its a typo that was missed by the spell checker. At least it was the right word, unlike 'waist' I'm legally blind in one eye, and losing my eyesight in the other from diabetes. I suppose that you'll want to slam me for that, too?
Great, I don't make friends with Nazis, anyway. I'd rather hang out with a bunch of lawyers, politicians, and used car salesmen than an anal retentive idiot like you.
With such a sleazoid attitude, chances are you got your DD214 as a result of "friendly" fire from your own unit. Do you carry a banner with you at all times?
BTW, you come across as the Dummkopf of all Dummkopfs.
Odd...the German side of my family arrived here in the US in 1859. National Socialism went back that far?
The opinion of a buffoon who thinks Nazism goes back to 1859, is noted and laughed at.
See above.
This is fascinating, watching you defend Nick the Dick.

That must really hurt, when he's wearing those stilettos. Oh well, that's what he gets for playing with himself, all day long. I have to admit that he types fairly well with just his nose.
