So I wash and wax my car the other day... and I notice thousands of microscopic rust dots all over my car. My car isn't even a year old and I wash and wax on a regular basis. I made sure salt was not on my car for more than a couple hours this winter. I wonder if I got something on it when driving through a contruction zone or something? They are mostly on the rear of the car though. Either way they do not come off very easily. Some don't seem to come off but I hope thats not the case when I work a little harder on it. Its almost like they are deep. It takes about 30 seconds of elbow grease per speck and there are tons of them.. I spent 5 minutes and only cleared a 5in by 5in area. The only thing that can touch the rust is Liquid Luster so far.. I am sure im destroying the clear coat when each spec comes off.

Anyone find this odd? I would expect it from an older car but.. I know there is a rust warranty on the car.. I don't know what to do.

 

i have the same thing i dont think its rust its just crap from a road theyre doing construction on by my house that i cant avoid...try using a clay bar and then buff it after that.

 

hmm post some pics and maybe I could provide some help but I would strongly reccomend trying a clay bar. It should work and wont ruin your clear coat.

 

I see ur car is also silver. I have a 06 Silver LS and when i went and hand washed it a couple weeks ago, there was rust and tar all over the sides of it, and on the roof. I must of spent a good 2-3 hours taking it all off using polishing compound and then going threw and waxing it. I talked to my dealer and all they pretty much did was try to sell me some coating that will keep it from happening and I laughed at them and walked out the door.
Good luck,
later

 

deff the clay bar will take care of that. I hate using the claybar though. Its so hard.

 

im haveing the same problem tiny redish brown spec on the back of my car will not come out for the life of me

 

I had this problem with my last cobalt,silver lt, I took it into the dealer and they told me it was just road rash, they took it in and detailed it for me and got those damn spots out

 

On my 06 being yellow you can see this quite easy.
Cleaner polishing wax seems to remove it.
I think personally it is hot carbon from the tail pipe sticking on to the paint.

I have read a tsb on this if you think it is rust .
#05-08-51-008A Bumps or Rust Colored Spots in Paint Due to Rail or Iron Dust (Remove Rail Dust) - (May 17, 2006)
Somthing about coming from rail dust from when it was transported on the Train.

 

I have the same thing on my yellow car. I found the clay bar from mothers does a good job. I have been told its a combo of many things.

 

Was just reading this post and it has the answer,
https://www.cobaltss.net/forums/general-cobalt-68/claybar-how-do-you-do-52703/

One of the many reasons for using clay is the removal of brake dust. Brake dust contamination, which attaches to painted rear bumpers and adjoining surfaces, is a metallic surface contaminant that can be removed safely and effectively by using clay.

Brake dust,the hot metal brake dust sticking to the paint and then oxidizing.
Would of neve thought of that one.

 

There is a TSB for this on our cars. I will have to get the number tomorrow at work, but it is due to railway dust on transport from the plant. The dealer will clean and detail the car for this.

 

i also have a silver car and i just used the meguiars clay bar then there 3 step polish system car looks AMAZING!!! after i did that i just use the quick detailer aftr i wash it no more tiny dots of anthing ANYWHERE... it worked GREAT

 

It's called "Rail Dust" from what my dealer told me about my car! Take it too them they will take care of it for you! They did for me! Its the dust kicked up while shipping the cars around on trains!

 

Yep, I got it too. I live down a dirt road, so I just figured it was specs of dirt that had worked its way into my paint.
