When it comes to protection against outside forces, thickness is an important part of the equation. Whether it’s a knight’s armor or a ceramic coating, a more substantial protective layer generally has more material to wear through. It’s for this reason many coatings require multiple layers to achieve their advertised durability.
This is especially important when you consider how thin a clear coat is. This factory-applied layer of clear paint is the only thing protecting the paint from the elements, and it’s barely the width of a post-it note. Use a buffer to remove scratches and it will be even thinner. While correcting the paint does remove a small amount of clear coat, applying a coating afterward helps add protection on top of the newly corrected surface.
Considering that, thickness can play an important role in coating durability and paintwork protection. It can influence how long a coating lasts, how much environmental abuse it can take before wearing down, and even how rich and clear the finish appears.
So how do you get to a thicker, more substantial protective system? Stack layer upon layer? Not necessarily. The answer lies within Dr. Beasley’s new Nano Surface Primers.
How Nano Surface Primers Build Thickness
To get paint ready for ceramic coating, scratches, oxidation and other surface defects must be removed. Otherwise, every little scratch and scuff will be locked in, sticking out like a sore thumb. As we mentioned earlier, this is an abrasive process that removes some of the clear coat to level the finish. As you correct, you do lose a small amount of material, which is one reason the protection step afterward is so important.
Nano Surface Primers, on the other hand, are designed to refine and prepare the surface for optimal coating performance as you correct. As you polish, the NSP nanogel helps create a cleaner, more uniform, and more coating-ready surface than a traditional polish that relies on conventional oils or fillers. This improved surface condition allows a ceramic coating to spread more evenly, bond more consistently, and form a more complete, uniform, thicker layer.
Why Thickness Matters
Now that you know how NSPs help create a better foundation for ceramic coating, let’s talk about why thickness matters. The answer comes down to two things — durability and shine.
More Thickness, More Durability
It may take years, but even the most durable ceramic coatings wear over time. Abrasion will (very slowly) wear away at a coating, rubbing off microscopic amounts little by little. This is just one of many environmental factors involved in coating longevity, but it stands to reason that if you want a truly long term coating, one that lasts a half decade or more, total film build can be an advantage.
It’s not just long term durability we’re talking about here, though. Thickness can also matter in the short term, because it affects how much sacrificial material sits between the environment and the clear coat. Let’s say a bird dropping sits for too long on a coated vehicle. It becomes caustic in the sun, and forms an etch mark. With a thinner or more worn coating, that etching may reach the clear coat sooner. A more substantial and intact coating, on the other hand, gives the contaminant more protective material to work through first. That can allow more time to address the problem before it can do more permanent damage.
More Thickness, More Clarity
Thickness can have another benefit, apart from durability — enhanced gloss. A coating layer can create more visual richness by adding another smooth, reflective interface above the clear coat. That added layer can contribute to a deeper, glossier appearance, especially when the paint underneath has been properly corrected and refined first.
How Coating Choice Affects Thickness
Nano Surface Primers help create a better foundation before coating. But what about the coating itself? How do you know which are the most robust? One thing to look for is solids content.
Most ceramic coatings aren’t just coating material — they also have some amount of solvent mixed in to act as a carrier so the coating spreads out more easily. The solvent then evaporates in a process called “flashing”. This limits the amount of cured material left behind from a single application, since some of what you apply is carrier rather than final coating solids.
But there are other coatings with 100% solids — like Matte Paint Coating Pro and Nano-Resin Pro. These coatings have no solvent to evaporate, so they can leave behind more cured material in a single application than a coating with a higher solvent content.
Building the Best Possible Foundation
With clear coats so thin, having a durable coating to apply after correcting is important. Once the paint has been corrected, you want to add protection back over that freshly refined surface, and when it comes to protection, more cured coating material generally means more material available to do the protecting. Nano Surface Primers do not literally replace the clear coat removed during correction, but they do help create a cleaner, more uniform, more coating-ready surface so the coating that follows can bond more consistently and perform at its best.
