Ask 1,000 auto detail experts in the United States about DIY paint correction – and you’ll likely receive just as many different opinions on the matter – ranging from “yeah, it’s easy” to “never attempt it on your own.”
Paint correction is not a simple task. The removal of paint swirl marks in the clear coat requires time, patience, specialty equipment, and a detailing and preparation process that rivals professional custom paint jobs. But if you take the time, make the investment, donate some blood, sweat, and tears; it can be incredibly fulfilling to see the end product.
In this second edition in our The Beginners Guide to Car Detailing (Like a Pro) series, we’ll outline some of the facts about paint correction for DIY’ers, explaining what it is, how to recognize the warning signs, and outline the basic steps needed to complete this project correctly.
1. What is Paint Correction
In case you didn’t know, paint correction process involves removing imperfections in the clear coat (or finish) and ‘restoring it’ to better than the original condition. Professional paint correction involves a few important steps (which we’ll describe in detail a bit later).
- Cleaning and completely removing debris
- Wet sanding or leveling
- Waxing and Polishing
- Sealing the Paint
Some of the common imperfections that lead to paint correction include:
There are some paint imperfections that can be filled with automotive waxes or paint sealants – but essentially, it’s just putting duct tape on an open wound. In order to fix these paint imperfections, paint correction is required.
2. When is Paint Correction Necessary?
We talked a bit about the old Mr. Miyagi method of car washing and waxing (wax-on, wax-off) in previous articles. While this is a phenomenal way of learning karate, it’s actually the primary source of paint correction.
Let me explain.
When a car is being washed by hand or an automatic car wash, the concept is to apply soap (which helps to cut into the layered dirt), rub it on the surface (to break up the dirt), then move to another section. What happens when you’re rubbing dirt in the same area? The answer is simple; dirt is being ground into the surface or creating scratches in the clear coat – even when you’re using a microfiber towel.
The same concept applies to car waxing. While washing a car is the first step, not all of the debris is removed. In fact, sometimes drying the vehicle with a terry towel will leave a microscopic residue that is jagged-edged. When the wax-on/wax-off method is used, you’re simply grinding those loose particles into the paint’s protective layer.
The only way to fix the scratches and swirl marks that are ground into the paint clear coat is through paint correction.
3. Why is Paint Correction Important?
It’s generally assumed that paint correction is simply a visual enhancement, like breast augmentation for example. But, that’s not quite accurate. When your paint’s protective layer (also called the clear coat) is damaged, eventually dirt and debris will penetrate the surface. This leads to paint chipping, sun damage, and premature fading.
To keep the paint looking clean, fresh, and shiny, many car owners visit detailing or auto body repair facilities to have them complete paint correction – or attempt it on their own. Paint correction essentially fills in the gaps, then applies a protective layer (like a ceramic coating or paint sealant for example), that helps to reduce the potential of this occurring again.
4. What’s the Process for Completing DIY Paint Correction?
So – you’ve made it this far into the article and still wish to attempt paint correction on your own? Sounds good! Just remember, the steps listed below are GENERAL in nature. It’s always recommended to consult with an auto body expert to determine whether paint correction or respray is the best course of action.
Noted below are the general steps for removing swirl marks on your paint. Any other type of paint damage should be repaired by a professional – trust me on this, I’ve attempted some advanced paint correction stuff and paid the price.
Step 1 – The Preparation Process
The first step in any corrected paintwork project is prepping the vehicle. This begins with washing. If you took the time to review the video above, you’ll see that they used a wax and polish stripping product called Chemical Guys Clean Slate. This stuff is actually really good, and something I’d recommended for serious automotive enthusiasts that clean, wax, and polish their vehicles frequently.
Here are the general steps you’ll want to complete during the preparation process:
- Wash the car using the TWO BUCKET method (as described in the video) with a high-quality wax removal cleaner.
- Use a Nanoskin AutoScrub bar (or similar product) along with CarPro Iron X (or similar product). This helps to remove tiny particles trapped in the clear coat so that you’ll have a fresh canvas to work on.
You’ll notice that I left out using a clay bar. Well, honestly, the products listed above are much easier and more effective at removing small contaminants – which is a huge benefit for DIY’ers.
Step 2 – Leveling
In the video, they called this phase paint correction – which is a three-step process; leveling, polishing, protecting. Here, you’ll use an electric polisher (or sanding wheel) combined with several quality microfiber cutting pads and a high-quality cutting compound. The product they used in the video (Menzerna Cutting Compound) is another really good choice for this type of paint correction project.
Here are the general steps for leveling the paint surface.
- Apply cutting compound with an electric polisher and microfiber cutting pad.
- Make sure to replace the microfiber cutting pad frequently – I’d suggest every six-square foot section. If you don’t replace the pad, you’re basically just digging a deeper hole.
- Complete this process until you’ve done the entire vehicle – or area you’re focusing on.
Here is the difference in a DIY vs. Professional paint correction process. A professional would not use a cutting compound – they’d likely color sand. However, this opens up a huge can of worms if you don’t know what you’re doing – so stick with the cutting compound and “buffing” method.
Step 3 – Polishing
If you completed the leveling step correct, you’ll be looking at a rather dull finish. This is where the polish phase comes into play. In the video (seriously – it’s that good for DIY paint correction projects) you’ll notice they used CarPro Essence Polish, which not only polishes but fills in tiny scratches in the clear coat caused by the initial leveling process.
For the polishing step, use this method:
- Always start with a brand-new polishing disk and pad. This will ensure you don’t spread excess cutting compound ‘residue’ while you’re polishing.
- Apply in a pattern that follows the body lines of the vehicle (they show an example of this in the video).
- Keep changing the pads frequently – and with each coat of polish. It’s generally a good idea to apply 2 to 3 coats of polish on a recently leveled clear coat.
Step 4: Sealing and Waxing the Vehicle
At this point, the actual paint correction has been completed. However, the job is far from finished. If you’ve followed each step and took your time, it’s quite possible that you’ve done a pretty good job of removing the paint swirls on the painted surface.
Now comes the paint protection step – which is arguably the most important as it will set yourself up for either frequently repeating all four steps or chillaxing and enjoying a showroom shine with an exceptional layer of protection.
So – in this step, we’ll give you two options:
Option A: Waxing and Polishing the Vehicle
In the video, the guys used a water-activated wax product, that when activated provides hydrophobic (water-repelling) properties. The other option is to complete a traditional car sealant + wax treatment. The problem with both of these methods is they will both wear out sooner than you’d like (likely less than a month or two), leave your already thin clear coat exposed to the elements – and require constant maintenance.
Option B: Use a High-Quality DIY Ceramic Coating
The other option (not discussed in the video) would be to apply a high-quality DIY nano-ceramic coating (like Armor Shield IX for example). A nano-ceramic coating provides an incredibly hard layer of protection, that fills in the microscopic peaks and valleys found in the paint surface. It’s also the best way to extend the lifespan of your paint. Further, a professional grade DIY ceramic coating can last up to five years if properly installed and maintained.
5. Wrapping It Up
A professional detailer can charge up to $2,000 for some paint correction services. While there are certain projects you want to leave to a professional, the methods and steps we listed above for removing paint swirls work quite well. The important item you need to consider is how you’re going to prevent this from happening again.
Take some time to learn more about DIY nano-ceramic coatings; as you’ll quickly discover why it’s becoming the product of choice for not only protecting your vehicle – but also making it easier to wash and producing a long-lasting brilliant shine.
