Surface Contaminants
Surface contamination are subjected to a myriad of potential contamination sources that can be categorized based the typical size of the particles and what they are made of, they are either organic such as bird excrement, honeydew and bug carcasses or inorganic such as brake dust, bituminous asphalt, etc .
Be cognizant that there are two types of paint contamination, above surface; Bituminous Asphalt (tar), Industrial Fallout, Tree resin (sap) and etc) which should be removed with detailers clay and / or a chemical paint cleaner and ferrous oxide particles (brake / rail dust) which should be removed with a decontamination product
Sintered ferrous oxide particles (brake / rail dust) penetrate the paint surface and if not removed will act as a conduit to the paint matrix system. Once water and heat (reactivity) is added the corrosion process is started, often showing ‘rust spots’ (blooming) on the paint surface, light colours tend show the necessity of decontamination more that darker colours. I am referring to those small brown ferric oxides (rust spots) that just seem to get larger and larger.
An untimely lawn sprinkler, a springtime shower, or spots that remained after washing, the minerals are white calcium/sodium deposits that are alkaline-based, especially from hard water. If left on the vehicle paint surface they act the same way as acid rain in that they will etch the paint film surface.
Brake dust or rail dust is very small, almost microscopic particles of steel, iron or their alloys. These particles carry a positive charge (due to friction) while the vehicles they land on are carrying a negative charge. The vehicle surface becomes a magnet, attracting and bonding the ferrous metal particles to the vehicle surface.

I am referring to those small brown ferric oxides (rust spots) that just seem to get larger and larger.
The corrosive chemical compounds generated then proceed to etch (corrode) the clear coat, the metallic particles (brake dust) penetrate and act as a conduit spreading the corrosives through the paint film system (and the sheet metal), which results in erosion of the paint surface, that shows on the surface as tiny rust spots (rust blooms) This is most noticeable on light colored paint surfaces (especially white)
Surface
Industrial Fallout [: simply a by- product of manufacturing, traffic, and factory pollution. These airborne particles settle on your paints surface causing contamination.]
Environmental Stains [: insect stains, bird droppings, tree sap, and acid rain spots are amongst the contaminants detailing clay will remove. [1]
Sub-surface
Rail Dust [: (ferrous oxide FeO) from the day a new car is shipped its surface is under attack. The railcar its sitting is showered with airborne metal particles from the rails. These ferrous metal particles embed themselves into the paint and will eventually oxidize and form rust corrosion under the clear coat]
Brake Dust [: sintered ferrous oxide FeO) particles from your own and passing vehicles will also get embedded in your paint.]
Automotive paint systems are porous; when you add water and heat to an acidic substance it will erode the paint system very quickly (the heat opens microscopic fissures in the clear coat allowing ingress, the water provides a carrier system for the acid, and heat acts as a catalyst each time water is reintroduced the acid will be reactivated). The paint surface should be periodically neutralized / decontaminated, i.e. once every two years (See also Reactivity)
The only way to completely remove sintered (heat fused) ferrous iron particles is with a dedicated decontamination system that opens up the paint`s pores to release iron particles and to neutralize the caustic compounds that have developed as a result of the particle. In one step, you can eliminate both the cause and its effects.
Detailer’s Clay vs. Decontamination
Before the advent of detailer’s clay it was a common practice to remove paint-overspray with a one-sided razor blade and a surface lubricant or by polishing the surface with a compound / polish and a wool pad.
a) Detailer`s clay - removes paint surface contaminants i.e. it abrades the top section of an iron particle, leaving what is below the paint surface to remain. Once water and heat (reactivity) is added the below surface particulates act as a conduit and the corrosion process is started.
Detailer’s clay is essentially a malleable applicator that contains suspended abrasive particles, used with a surface lubricant it aquaplanes across the paint surface and removes surface contaminants by abrasion and then encapsulation by the malleable polymer and was originally formulated to remove paint overspray; it is also useful for removing surface contaminants that have bonded to the paint.
Detailer’s clay was originally formulated to remove paint overspray; it is also useful for removing surface contaminants that have bonded to the paint surface. It gained its reputation as a decontamination method because it was mistakenly believed that it ‘pulled’ brake / rail dust iron particulates from the paint surface. Detailer’s clay contains abrasives that will only shear any brake dust particles leaving what is below the paint surface to remain. Once water and heat (reactivity) is added the corrosion process is started.
.
b) Paint decontamination systems were developed as a method of removing ferrous contamination beyond what can be removed by washing or claying alone. The only way to completely remove sintered (heat fused) ferrous iron particles is with a dedicated decontamination system that opens up the paint`s micro pores to release iron particles and to neutralize the caustic compounds that have developed as a result of the particle. In one step, you can eliminate both the cause and its effects. Ongoing damage is immediately stopped and future damage is prevented by completely removing the ferrous particles.
Detailers Clay
Detailer’s clay is made from Polybutene; it was originally invented and patented in Japan in 1987. Tadao Kadate is generally acknowledged as the inventor of automotive clay resin for the removal of paint over-spray. It is formulated with mild abrasives, a common misconception about using detailer’s clay is that it pulls contaminants from the paint, and if this were true there would be no need for it to be abrasive. Be cognizant the using a clay bar can actually add minor imperfections in your paint so it`s always best to follow up with a polish to remove any clay induced micro-marring.
First used by Japanese auto manufacturers on vehicle production lines and then auto body repair shops, the technology was passed on to the US market in the late ‘90’s. Detailer`s clay is now routinely used by OEM`s, professional detailer`s, vehicle auctions and body shops as a simple, safe way to remove paint over-spray, tree sap and industrial fallout from both vehicle paint and chrome and glass surfaces
Regardless of how clean you think your paint is, there are still contaminants stuck on the paint that you need to remove before waxing or polishing your paint. Road film, oil, tar, grease, water spots and other environmental contaminants bond to the paint and glass surfaces and are difficult to remove. Glass and especially the windshield and rear window on trucks and SUVs are prone to these surface contaminants.
Corrosion
Detailer`s clay and decontamination are two different processes. The abrasives `shear` the surface contaminates, the sheared particles are then encapsulated by the clay (i.e. the top of the metallic particle leaving the rest embedded in the paint, which acts as a conduit for moisture to the various paint layers, allowing it to continue generating corrosion damage
While clay products are useful for removing paint overspray (this is what the product was originally formulated for) and cleaning surface contaminants, it cannot permeate and deep clean the pores of the paint. So unless a paint decontamination system is used; heat and moisture will react with the metallic particle and continue the corrosion process
Brake dust or rail dust is very small, almost microscopic particles of steel, iron or their alloys. These particles carry a positive charge (due to friction) while the vehicles they land on are carrying a negative charge. The vehicle surface becomes a magnet, attracting and bonding the ferrous metal particles to the vehicle’s paint surfaces.
The corrosive chemical compounds generated then proceed to etch (corrode) the clear coat, the metallic particles (brake dust) penetrate and act as a conduit spreading the corrosives through the paint film system (and the sheet metal), which results in erosion of the paint surface, that shows on the surface as tiny rust spots (rust blooms)
Environmental damage to paint comes in a varied range of threats; acid rain, road salt, tree sap, hydrazine an extremely active acid that is found in jet fuel, industrial fallout, ultra violet radiation (UV-A and B) and other airborne contaminants are very detrimental to a vehicles paint film surface. They are all forms of environmental contamination and given the right catalyst; reactivity (heat) plus moisture, they will become acidic. During this process the metal absorbs oxygen from the water and forms iron oxide (rust). Given the porosity of paint they permeate the paint matrix down to body metal.
Although present on all paint surfaces, sintered brake / rail dust is most noticeable on light coloured paint surfaces, especially white. These contaminants are invisible to the naked eye, once they start to oxidise, and turn orange; this is when the problem will be brought to your attention, even on brand new vehicles.
Stages of Corrosive Paint Damage
Stage One- Iron particulates causing surface staining leading to substrate corrosion
Stage Two - Contaminants have permeated the paint matrix causing discoloration and corrosion damage
Stage Three - Particulates and corrosive compounds causing severe damage to the paints resin (binder) system
Signs of Paint Surface Contamination
• Dark coloured specks
• Brown or Orange (rust) coloured stains or specks
• Yellow stains
• Small metal coloured flecks
• Rough texture
• ‘Water spots’ or marks
• Surface etching
• Oxidation
• Paint ‘stains
In this case, paint care not only serves aesthetics, but also helps preserve the vehicle and its resale value
