I'm sure every car detailing enthusiast understands how important it is to protect your car's paintwork in perfect, glossy condition.

A single coat of ceramic coating will provide excellent durability and hydrophobic qualities. 

However, it is inevitable that due to the weather conditions, direct sunlight, acid rain, bird droppings and other factors a second coat can become necessary. 

Even if your first coat has been applied in a professional detailers these factors can still reduce its appearance.

In this blog post, I will explain the three signs that indicate it's time to apply a second coat of ceramic coating to your car's paint.

Fading or Diminishing Hydrophobic Effect

A popular feature of Ceramic Coating is its ability to create a super hydrophobic effect. This means that after each shower of rain or indeed after every wash the waters beads up and rolls effortlessly off the car surface.

But over time this hydrophobic effect may start to fade and water droplets may not separate and bead up, but stay in mini puddles on the surface. Causing a more dabbled effect with irregular shape poodles of beads instead of the regular form of a hydrophobic layered surface.

This is the most noticeable indicator that the original coating is losing its properties and wearing thin and a sure sign that the initial application needs a second ceramic coating is needed to restore its effectiveness.

If hydrophobic properties such as surface beading is important to you then we can recommend the following Ceramic Coatings.

Surface Scratches and Swirl Marks

Unless your car never leaves the garage it has to be susceptible to contact with everyday items that can cause swirl marks or surface scratches. 

These can be caused when you wash your car if you're not using the correct method. By road debris such as rock salt chips or may other environmental factors

Your first layer of ceramic coating will protect and absorb many of these abrasions but repeated exposure to these situations will gradually wear down the effectiveness of the coating.

Noticing  a number of light scratches or swirl marks on the surface of your car is also an indication that the current ceramic coating is losing its properties and may benefit from the application of  a second coat.

And a good overall paint correction could be employed to ensure all faults are reduced.

Loss of Gloss and Shine

Any new coat of ceramic coating creates incredible depth of gloss and an enviable shine that turns heads everywhere you drive.

However, due to exposure to UV rays, harsh weather conditions, airborne pollutants and just the passage of time a coating will lose its luster.

If you notice a significant dulling or lack of deep shine in your ceramic coating then this is a clear sign it's time for a second coat to liven up the older one.

Therefore, we have put together a second coating plan to prepare and apply a coating.

Here it is a Step by Step guide to applying a second layer of ceramic coating.

Prepare the surfaceEnsure the car surface is washed thoroughly with a pH neutral shampoo. Ideally use a foam cannon and the two bucket wash method to remove all grime and grit. Next, give the entire vehicle a full clay bar to remove all surface contaminants. Final stage of preparation is to use a good polish to give any paint correction that is needed. As it is essential for best results the original ceramic coating is as perfect as can be.
InspectionInspect the whole car paint for signs of fading, poor hydrophobicity or lack of glossy shine. Equally as important, check for any areas that may have sustained any damage or become completely worn out. As these could need more than one coat.
Surface DecontaminationTo get the best results from applying a second ceramic coat it is essential that the surface is decontaminated. This is best done with  isopropyl alcohol solution wipes. This step is crucial to ensure proper adhesion of the second coat on top of the first coat.
Application of the Second CoatProperly mix the ceramic coating product by shaking it well.  Start by applying a small amount to an applicator pad and test it on a small inconspicuous area to ensure good coverage. Apply the coat to a small section at a time, making sure the application is even and in straight lines. Overlap each section to ensure complete coverage. Avoid applying too much pressure to prevent streaking.  Give extra attention and an additional layer to areas identified as faded or worn off.  Follow the recommended curing time before moving to the next step.
Curing and ProtectionOnce the curing period has elapsed, use a microfiber towel to gently wipe away any high spots or excess coating. The newly applied coat should not be exposed to rain or water until it has finally cured.
Maintenance and AftercareFollow the manufacturer's guidelines for post-application maintenance and aftercare. Regularly wash and maintain the ceramic coating to prolong its durability.
