Default Rust Spots in Paint

I have a 2007 White Tahoe. In fall last year, I spent 6 hours with a clay bar removing all the rust spots in my paint. They were all pin sized to pencil point sized. They were all over the car including on the bumpers and rear hatch. I then waxed the car as normal with Mequiers. To my shock, today I see the spots are coming back! Anyone have same problem? Any permanent fixes available?

The problem should have been corrected during the pre-delivery inspection. You may have a ahrd time going back on GM for it, but at least this bulletin gives you details on how to remove it...


#05-08-51-008B: Bumps or Rust Colored Spots in Paint Due to Rail or Iron Dust (Remove Rail Dust) - (Apr 23, 2007)

Click the image to open in full size.
Subject:Bumps or Rust Colored Spots in Paint Due to Rail or Iron Dust (Remove Rail Dust)

Models:1994-2007 GM Passenger Cars and Trucks (Including Saturn)
2003-2007 HUMMER H2
2006-2007 HUMMER H3
2005-2007 Saab 9-7X


This bulletin is being revised to add Saturn models. Please discard Corporate Bulletin Number 05-08-51-008A (Section 08 -- Body and Accessories).
Condition

Visible rust colored spots or bumps on a vehicle's paint surface from rail or iron dust.
Cause

Rail dust comes from tiny iron particles produced from the friction between train wheels and the tracks and gets deposited on the vehicle surfaces. Iron dust can get deposited on the surface if the vehicle is stored near any operation producing iron dust such as a steel ore yard. Either material can lay on top of , or become embedded in , the paint surface.
Correction

Because the severity of the condition varies, proper diagnosis of the damage is critical to the success of repairs. Diagnosis should be performed on horizontal surfaces (hood, roof, deck lid, pick up box, etc.) after the vehicle has been properly cleaned. There are two types of repair materials recommended to repair rail dust or iron dust:
  1. GEL TYPE OXALIC ACID: - Has the characteristics of the liquid type oxalic acid but stays where you put it because of its gel consistency.
  2. CLAY TYPE NON-ACID BASED: - Requires surface lubricant during use.
    - Has different grades available.
Caution: Rail dust remover (Oxalic Acid) is an acidic substance containing chemicals that will break down the iron particles embedded in the finish. When working with rail dust remover, use the necessary safety equipment, including gloves and goggles. Follow the chemical manufacturer's directions closely because it may require special handling and disposal.
If, upon inspection, some particles are still present, the various chemical manufacturer's processes can be repeated.
After the removal process, small pits may remain in the clearcoat and can be corrected, in most cases, with a finesse/polish operation.
Procedure
  1. Move the vehicle to a cool shaded area and make sure that the vehicle surfaces are cool during the removal process. DO NOT PERFORM THE REMOVAL PROCESS IN DIRECT SUNLIGHT OR ON A VEHICLE WITH HOT OR WARM BODY PANELS.
  2. Wash the vehicle with soap and water. Dry it immediately and clean the affected areas with a wax and grease remover.
  3. Perform the removal process according to the chemical manufacturer's directions.
Once the damage has been repaired, the final step involves a polishing process.

Thats not a super-rare occurrence among any make. Ford had a fit with their 98-00 F150s.

I also have a white 2007 that is doing the same thing. I just bought it used december of 2008 with 36858 miles on it . If you decide to contact the dealer please keep me informed on what they say. I doubt they will do anthing seeing how it was supposed to be taken care of during pre delivery.

I have them on my hood, they are very hard to see in direct sun light but can be seen during the day in the shade of a building.
I was going to try the clay bar....every white vehicle I have owned has had them it seems...

a picture from my hood, some of it is dirt as it rained yesterday and I haven't washed it yet...the brown or rust ones are them the black ones are dirt.
this was a pretty good picture of it, but to be honest you really can't see them unless you are right up on it and are looking for them.

Default covered?

so... is it covered under the 6year 72k rust warrenty? or is this out of pocket?

I think I recall a 1985 to 1990 something where all the cars paint rusted off the hoods / roofs because they didn't use a primer... whoops (not all cars; but a lot of american ones)

some new paint that wasn't supposed to need a primer..?

good luck i own a 2007 silverado and my buddy ownes a 2008 silverado both have them. dealer told me claybar also, after they said they fixed the problem, which they didnt. i talked to a reputible paint shop and they told me to fix correctly is to remove clear coat and respray. they told me to go after gm to fix, cause its not right. the body shop has had a few calls about the same problem and he tells them to to go after gm. using clay bar or chemicals are no good for the integrity of the paint and should be done right. i live about an hour south of chicago and now the dealer is saying its the weather that i live in, come on! they shouldnt sell these darn trucks around here then. am i supposed to leave it in the garage all year. i say contact gm directly like i did. nothing has happened yet but never no.
