Rail Dust and degreasers

[JayGXP]

Has anyone had any luck with getting rid of raildust with a paint safe degreaser.? Clay bar isn't doing the job on some spots.

if so which ones?

I know they are out there. But ones I have come across all cost around 60-100 bucks.

Try some rubbing compound.

If a degreaser is strong enough to remove imbedded contaminants from your paint, you really don't want to use it as it will dull your paint significantly. I wouldn't even try it to be honest.

*dang*.. Yea I don't know what to do with some of this. Claybar does wonders on most of it... But there are a few spot that no matter how many times I go over it it wont come out.

I need something like when people wax their body. Something that will grab the dust and pull it out. It seems like the claybar is just smoothing out the surface and leaving the embedded stuff behind.

Anyone else deal with pesky dust that they just couldn't rub out?


Doesn't a rubbing compound scuff the clear coat though? to where I'd have to polish after.. not like I'm not going to anyway but still.

I love my car to death, but *dang* the white.

A rubbing compound will definitely leave the paint looking bad. If you were in the area we could hit it up with my polisher, but that is a ways to go for a couple spots

You can try something like this...http://www.autogeek.net/d20130.html, http://www.autogeek.net/mg13001.html



I do detailing and it's something I've used many times with great results. Hasn't harmed any car I've used it on either.

One link is the spray bottle, other is the product.

GM happens to have a TSB regarding it.

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 an iron 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.
