Paint Defects and Paint Correction – Part 1: Swirls and Scratches

by

What is paint correction and how does it improve the appearance of your vehicle?

If you are a Professional Detailer you often have had a potential client say “my car is missing that pop”.  But when you bring up what is visually obvious to your trained eye, the person responds by saying “it does not have any swirls!  I don’t see what you are talking about!  What is this paint correction talk!  It just needs a good wax!”

If you are a potential client discussing the needs of your car with a Professional Detailer, you may have thought to yourself “what is with this crazy paint correction talk!  He must be trying to con me out of my money.  Sure my paint looks dull, but I don’t see what he is talking about.”

What you do not see is making your paint look dull.

What is wax and what is polish?  Wax is for paint protection.  Polish is a product consisting of liquid abrasives designed to level and consequentially clean your paint in order to improve its appearance.  Many people mistakenly believe a wax is performing the way a polish would.

One of the reasons that this misconception is perpetuated throughout the mainstream public is that most waxes sold over the counter are cleaner waxes.  In other words, many over the counter products are all in one type products.  So upon application, the paint cleaners in the product are cleaning up the road grime and performing some of the duties a clay bar would perform.  These products were made knowing the average consumer is not going to be as meticulous as a professional or enthusiast.  In addition, some of these over the counter products also have built-in glazes that can fill in some of your paint’s defects temporarily.  Wax itself will slightly fill. The clarity this brings will dissipate as the wax degrades.  With a cleaner surface and a very temporary masking of some paint defects, the consumer falsely believes the wax is making a significant and permanent change to a car’s painted surface.

I believe this the number one reason there is so much confusion about what products actually do.  In the short run it helps the company sell a product with a result.  In the long run confusion by oversimplification has created more problems for the budding enthusiast and the professional trying to educate his or her clients.

Now answering what is wrong with your paint:

For perfect mirror-like clarity, you need a smooth/even surface for light to reflect perfectly (specular reflection) back to your eyes.

When there is an uneven surface, light waves are scattered at many different angles (diffuse reflection).  Consequentially your paint will look dull.

There is not a smooth signal to and from your eyes with a blemish.  Now imagine 1,000s of these!

swirls

These are referred to as swirls.  Many people make the mistake of thinking they come from a polisher due to an optical illusion created from direct sunlight.  But the circular pattern is really thousands of tiny straight line scratches if you look at them closely.  Your eyes trick you because of the pattern around direct sunlight is where your eyes are focused.  This is why the defects are known as swirls (swirl pattern around intense light).  They are primarily the cause of poor wash technique, that includes definitely includes hand washing.

The owner of this Jaguar did not see these swirls, yet he wanted me to “make paint his pop”, and he had yet to find someone who could address the problem.  Long story short, fixing the problem, meant paint correction.  As obvious as to some what was wrong with his car with the help of a swirl finding light, this is a relatively common issue.

Paint Correction is the use of abrasives (primarily polish) to remove defects by leveling the painted surface below the depth of the defects.  This, providing a level surface, improves the appearance of your paint.  Other terms that have been used to describe what paint correction is are cutting and buffing or buffing out.

Stage 2: Two Polishing Steps

This is the step for most noticeable defect removal.

A typically aggressive (compound) polish paired with and typically aggressive pad choice is used as the first of two steps.

This is followed by a finishing polish with a gentler pad choice that bridges the gap further refining and jeweling for mirror-like clarity.

Stage 1: Paint Correction

Although it is the primarily a resource for cleaning and maximizing gloss on weathered paint before applying protection, a slightly more aggressive pad or the use of a less aggressive compound with a medium light pad can produce respectable correction results in just one step.

When a majority of defects are not removed but leveled and rounded off to the point which the visual appearance is noticeably better it is often referred to as an enhancement of the paint.

All In One:

There is also an All In One type polish that can enhance the paint.  Though more efficient, there is a certain sacrifice when combining polish and wax in terms of effectiveness.

White cars:  even with the base coat color making defects much more difficult to see, an effective polishing session can yield a mirror like gloss even from these cars.

  4. This article is spot on. I have a local detail shop in Tampa FL, and i have had the same type of customers who think wax will fix their dull and swirled paint, often times its a head banging job to get the customer to understand what you the detailter is trying to get across…

    Good post well said
