FWIW I noticed the Cobalt chassis flexes very easily. I used the jacking points indicated in previous threads and had to open my passenger door with the rear in the air. I immediately noticed the door latch was hitting the striker at an odd angle. It was more difficult to close/open and I did not tilt the car at an angle. It was just lift in the air at the points right behind the forward trailing arm connections.

Not to sound like a dick but what does this have to do with GM putting little to no clear in our door jambs?

Well, what do you think is causing the doors to vibrate/rub against the weatherstriping so violently? The Cobalt is the first car I have seen where the chassis flexes enough that the paint rubs off the door or the door no longer closes properly when jacked using a unibody point.

Whether it has thick clearcoat has zero relationship with chassis flex/door wear. It would just wear through the clearcoat first. Like I said, when I lifted the car in accordance with the recommended jack points, the doors would no longer close properly.

I noticed the same wear pattern on my 09 SS/TC, and it came from the factory with 2 miles on the odometer. It is caused by rubbing against the weatherstriping when grit/dirt is trapped there. This is of course if you're referring to the photo of the yellow cobalt where the metal is rubbed bare. I used some leftover 40mil paint protection film (used for my X-Pel headlight film) and covered up that area. I would recommend keeping that weatherstriping clean though.

Their are alot of cars that flex like that, it rubs through from shutting the door, that is why it is worse on the driver side. And the fact that they put barley any clear on the jambs makes a big difference. I did mine a year and a half ago and it's perfect. "better than new"

As far as the weather stip keeping clean. I only drive my car in the summer and i wash it 3 times a week, it's kept spotless. Yes the yellow car is my wifes and i just redid her doors today. I did the same thing as mine, sand blasted the bottom, epoxy primed the bottom, seam sealed around the whole door and painted it. I also put the 3m chip gurd tape on the bottom edge.

**** mine isn't as bad as it could be but the pant is scratched to hell where its been im guessing flexing against the dirt and grime on the seal. got some silicon from work on it now. hopfully that will prolong the damage for some good miles.

This was never a problem on my 2.2, but checking last night my driver's side door is showing some marks in the same spot as the image. That said, my weather stripping is exceptionally dry so I'm going to be applying silicone imulsion to all my stripping tonight which I suspect will help the issue. I think when it gets hot the stripping simply sticks horribly to the paneling resulting in the damage we're seeing.

I decided to check out where it was rubbing last night before applying the Emulsion to my weather stripping. It seems to me the rear corner of the bottom stipping is somewhat lacking in any form of support so there is potential for the door to rub constantly during normal driving. That said, I applied the AC Delco product to the stripping in my trunk, doors and sunroof so I'll keep an eye on it to see how it works out. First thing I noticed is that my sunroof has stopped crunching and cracking like it was before it was applied, the product was just tough to tell whether or not it was being soaked up by the weatherstripping or just hanging out on top. I'll keep an eye out (I cleaned off the residue from the door rub) and see if things improve.

As for the dirt collection it's because of where the stripping stops and there is still enough door gap for dirt to get in there during normal use, and living in on a gravel drive you're probably bringing in rocks with you that land in the door frame and eventually work their way towards the back. I can only imagine it making one hell of a mess of the paint if a pebble got in between the two on a long road trip .

They insist that those BF Goodrich tires are responsible... Maybe its just their paint is cheap, thin and falling off the car? Oh no, that can't be happening...

It's not like GM never had a paint issue on their 90's cars.
That's all I see around upstate NY...
but I guess they don't have factory tires either

so far, the condition inside the door jambs is not happening. My 2007 Cobalt SS/SC still has all of it's paint in the jambs and on the inside of the door. Not showing any sign of wear. Also, when jacked up (when I painted my calipers), i opened and closed the door with no issues.

Mine is doing the same thing and nicely enough it's actually started to wrap around to the outside of the door. Car is long out of warranty though so i guess once it's mine i'm just gonna paint the whole thing. tons of stone chips all over the car anyway.
