Let the boy go !
Salt #1. Getting wet and drying continues the process. Cars underwater take a long time to rust due to lack of oxygen.
67-69 Dart Converts drain any water that gets past the body and the top, INTO the inner quarter by the rear quarter window. It is intended to drain out the body drain holes on the pinch weld under the car.I learned this is because 2 doors have a direct path from the wiper seal below the rear side window, to the pinch weld of the outer wheel house and quarter panel.
That's funny...Don't park your car in a chicken coop

Interestingly they don't typically rust in that area.
Behind the rear wheel in the lower quarter, yes,
On the front floor pans, yes
Did someone say chicken coop?Don't park your car in a chicken coop.
To be clear, I'm not talking about your typical rust in a quarter panel or floor. I'm talking rust EVERYWHERE on a car; the rust leaves a car as swiss cheese, where there's not much to work with.
Background: I'm in Missouri. We salt our roads. I know how much rust my cars get every year, but some of my cars...I wonder if they lived in a lead-acid battery plant before I got them. My '75 Valiant is an absolute rust bucket. The tops of the quarter panels have rusted out. The friggin' dashboard rusted out. It seems like it's continued to rust despite being mostly parked for a decade.
My '72 Dart on the other hand, has sat for more time, I've owned (and not maintained) it longer than the Valiant, the top rotted off exposing the unpainted roof to the elements, and it hasn't really rusted much at all through the years.
I have two '92 Dakotas....Same thing; one truck had the frame rust through where the rear cross member bolted up. The upper windshield frame has rusted through in places. It's just RUSTY. The other truck...clean. Nothing more than surface rust, and that's even limited. They've both been in Missouri for the last 25 years.
So, I've heard everything from "thinner sheetmetal after '72 to save weight for fuel economy" to "St. Louis vs. Hamtramck vs. wherever", to "the battery ground is hooked up poorly or wrong so the body is being used like a sacrificial anode". I understand that region plays a huge role, but all of my cars have been in my possession in the same area for 20+ years. I've owned my Dart and Valiant since the mid '90's, and the Valiant floorboard was rusted out even then.
What say you guys? This "Daytona Superbird" is a good example. Even the chrome is rotted off the bumper! The deck lid is roached. It looks like it was driven through a puddle of battery acid. The car has clearly seen a repaint, but WHY is the rust so aggressive on this versus other cars?

Ya better buy them out of Ok Mo KS Ar, THEY are gold plated in Texas!!!!! (and still rusty!!) You could trade a case of super loud truck mufflers to the locals as a down.... go figure!!!I guy could make a living bringing those old rust-free "work trucks" here to the rust belt. Cars too.....
A lot of truth there. Every model and brand has their rust issues, and not always in the same place!The first time I noticed the phenomena listed in the thread title was in the mid 1980's.
I noticed that 66/67 B body cars, as well as 70-72 mone carlo and 71/72 torino didn't rust out nearly as bad as 68-70 Mopar B bodies and both earlier and later fomoco and gm intermediates.
I started my Mopar journey as a 66/67 B body guy, so I became intimately familiar with them.
Another thing I noticed was that 2 door cars, if they did rust, rusted bad above the rear wheels.
4 door cars did not.
I learned this is because 2 doors have a direct path from the wiper seal below the rear side window, to the pinch weld of the outer wheel house and quarter panel.
4 doors have the back door, and another layer of sheet metal in the way.
I don't think that was dirt, man...That's funny...
My 67 Dart convert #2 was a chicken coupe according to the guy I got it from. I did find feathers but mostly dirt, 70 lbs so far. Not an exaggeration, I measured it all.
LOL!I don't think that was dirt, man...
If they sit out in the weather with the windows rolled up, water gets inside past those old seals, but can't get back out. Moisture is a rust magnet, even without salt.People do not believe me when I say, these old non rust belt cars mostly rust from the insides.
When i was stationed I Sacramento CA a long time ago, I knew a guy who bought up rust free California cars and trucks and shipped them up to a business up north (Michigan I think). He made a very good living doing that.I guy could make a living bringing those old rust-free "work trucks" here to the rust belt. Cars too.....
Back in the late 80s, early 90s. (before the first Mopar price bust,) there were some guys in Mn. that did that. They did well. The first bust was in 1990. But it took another year before the word really got out, and the high end "investors" folded and stated to pull out. Pull out meant them selling their high $ hemi E body to another high $$ buddy with the cash, to save their ***.When i was stationed I Sacramento CA a long time ago, I knew a guy who bought up rust free California cars and trucks and shipped them up to a business up north (Michigan I think).

Interesting! How does that work on ships and how could that be done to our cars?Has anyone ever tried using a sacrificial anode like they do on ships?
I am not sure it would on cars as a boat is grounded thru its contact with the water, a grounding rod like your home has with a lead to the car might do the trick.Interesting! How does that work on ships and how could that be done to our cars?
My 66 Belvedere sat in a cow barn for a very long time, it had light surface rust all on top sides, nothing under or inside of car, even quarters are rust free. Cowl was bad because of a rats nest using headliner material. Replaced that from a doner carA lot of truth there. Every model and brand has their rust issues, and not always in the same place!
I agree, the outside of early B does not rust near as bad a outside of 68-79 B. Why>>> Dunno. But if the cowl has rusted and water gets inside the car, then the floors go..on any of them! Like mentioned, did the car sit under a shed most of its life or under a tree..any kind of tree?
I have had many people tell me sitting on grass is the issue. I have had some sit on grass for years, no issue.
Yes, acid rain. Plain rain. Yes humidity. How many cars came to Tx or Az from some years in the rust belt?
I have bought rust free hemi, and 6 pack cars out of Mn. with NO rust because they were considered special and never driven on salt!
I bought a 70 Charger RT about 2000 that sat on the dirt in a budy's small private boneyard on its floor for years, NO suspension and when we pulled it up and put it on my trailer, the floors were perfect! WHY? The cowl was solid, windows had always been UP, the weatherstrip was still sealing, sat under NO trees, and they oiled the dirt down every year with used oil NO weeds!!!!!
I have a bud that owned a hemi 67 GTX since the 80s. Rrural N. Mo. It never sat under a roof , he hid it in the woods on his brothers farm, etc. Solid old car that had not been on the road since the 80s. Then in the late 90s he did a complete resto, body/paint, interior, new bumpers, etc. Great job. The it sat in his enclose pole barn "garage", on limestone gravel for about 3-4 year UNDER a store bought car cover of some brand, and when he uncovered it the first time in 4 years, the new bumpers had rusted bad , the paint looked like crap, the interior was full of mold, and rat pee, you get the idea.
66-7 B bodies did not tend to rust near as bad a 68-70 B bodies., in general. Much better sheetmetal. But funny as they never bring the $$$ of a 68-70.My 66 Belvedere sat in a cow barn for a very long time, it had light surface rust all on top sides, nothing under or inside of car, even quarters are rust free. Cowl was bad because of a rats nest using headliner material. Replaced that from a doner car
