My car is brand new!\u00a0 My car was just washed!\u00a0 It had been detailed by the dealership!\u00a0 Why would my car need a clay bar treatment?\u00a0 Why would it need any sort of decontamination?<\/p>\n

Many professionals (including myself) hear these statements quite often.\u00a0 The picture below showing the brown spots, is bonded contamination taken off a very small section of a recently purchased car from the dealership.<\/p>\n

\"\"<\/p>\n

Unwanted grime and pollutants that stick to your paint (washing with car soap does not remove) are bonded contaminants.\u00a0 Decontamination is the process of removing these foreign substances from your painted surfaces.\u00a0 Mineral deposits, road tar, tree sap, airborne pollution, paint overspray, industrial fallout, and rail dust are examples of contaminants that if not removed promptly bond the paint surfaces.<\/p>\n

Think of your skin.\u00a0 It breathes, has pores, and also has dirt that can clog those pores.\u00a0 Paint has a lot of similarities to your skin in that respect.\u00a0 If you can imagine washing your body with a body wash, that would be the near equivalent of using a ph neutral shampoo on your paint.\u00a0 Like skin your paint may need something somewhat more aggressive, similar to an exfoliation or face scrub.\u00a0 You have products that remove oils, exfoliate skin, and pull impurities out of the pores of your skin.\u00a0 Paint decontamination is akin to a more thorough kind of skincare.<\/p>\n

“Are you saying that after washing my car there is likely still grime, that you call contamination, still on my paint?”\u00a0 Yes!<\/p>\n

Even if you purchase a car brand new from the dealership, ask yourself how it arrived to the dealership?\u00a0 Many cars are transported by train where they are bombarded by rail dust.\u00a0 Even before arriving most cars are exposed to the outside environment.\u00a0 These cars will also often be exposed to airborne pollutants parked at dealership lots.\u00a0 Once sold, dealership car prep is usually not as thorough of a process as a detailing from a car care specialty shop.<\/p>\n

Some of the most heavily contaminated cars I have worked on have been recently purchased vehicles.<\/p>\n

\"\"<\/p>\n

Iron remover products like the one shown in the picture above (on the right) remove ferrous metals and fallout.\u00a0 Tar remover like the one shown in the picture above (in the middle) and some All-Purpose Cleaners are good at removing tar, bug guts, traffic film, and some other mild contamination.\u00a0\u00a0 Waterspot removers like in the picture above (on the left) can get rid of the mineral deposits, removing water spots that have not etched into your paint.<\/p>\n

There is the clay bar a better all-round tool (more on that later).\u00a0 There is polish that not only levels paint to remove\/minimize micro-scratches, but also abrades away oxidation (similar to removing dead skin).<\/p>\n

If there was one product that covers all of these products it would be the clay bar.\u00a0 But what is a clay bar and what is its importance to detailing?<\/p>\n

\"\"<\/p>\n

A history of the clay bar and its influence on detailing:<\/strong><\/p>\n

Once upon a time wet sanding or a very aggressive rotary with the compound combination was considered necessary to yield showcar results.\u00a0 The use of sandpaper is incredibly aggressive and for modern thinner clear coats often impractical and or an irresponsible option.\u00a0 These methods meant to level a significant amount of paint, were also at the time the only methods known to thoroughly clean paint from bonded contamination.\u00a0 It is still common to see these practices take place at cheaper and faster detailing shops.\u00a0 These methods without a clay bar though will create severe holograms and other damage to a now more likely critically thinned clearcoat. Imagine washing a car with no lubrication.\u00a0 Polishing and sanding to remove existing contaminants has a similar effect.<\/p>\n

The benefit of a better quality polishing experience is evident, but there are other reasons why claying is important.\u00a0 A smooth surface is a more aesthetically appealing (glossy) surface.\u00a0 If your car was covered in dust, it would likely not be as shiny compared to a finish that had just been washed.\u00a0 Removing the invisible contaminants bonded to your car improves its appearance.<\/p>\n

Quality protective paint sealants (synthetic version of a wax) usually need to bond with bare paint to work to its fullest potential.\u00a0 Contaminated surfaces do not allow a proper bond, increasing the likelihood of that 6-month sealant not lasting nearly as long as advertised.\u00a0 When applying a ceramic coating, it is even more important for a surgically clean surface.\u00a0 Unprepared surfaces, often contamination, can be the cause of many failures.\u00a0 As I am not a chemist, I am sure some sealants and perhaps even coatings are more forgiving than others in needing a surgically clean surface.\u00a0 But ensuring a bare surface would give me peace of mind I am getting the most out of a protective product.<\/p>\n

\"\"<\/p>\n

Even glass has bonded contamination that a clay bar will remove.\u00a0 I have also clayed wheels before applying wheel coatings.<\/p>\n
