How to Care for Your Gtechniq Crystal Serum Ceramic Coating

At Gavigan Detailing, I take pride in using Gtechniq’s Crystal Serum ceramic coating – a premium treatment designed to transform and protect your vehicle’s finish like never before. This advanced ceramic coating isn’t just about the shine; it’s engineered to offer outstanding durability, chemical resistance, and a deep gloss that lasts for years. Once applied, Gtechniq Crystal Serum forms an incredibly hard layer on your paintwork, which protects against UV damage, oxidation, and environmental contaminants. It repels dirt and water effortlessly, making your car easier to clean and helping it maintain that “just-detailed” look.

But even the most robust coatings need the right aftercare to keep performing at their best. After all, Crystal Serum isn’t a permanent shield – it needs to be treated with care to ensure it stays in peak condition. That’s why I’ve put together this guide to help you keep your coating looking as fresh as the day it was applied. Here’s how to look after your newly ceramic-coated car:

1. Wait Before Washing

For the first 7 days after application, avoid washing your car. This allows the Crystal Serum to fully cure and form its ultra-durable layer. During this time, try to keep your vehicle clean by parking under cover and avoiding wet, muddy roads.

2. Use pH-Neutral Car Shampoo

When it’s time to wash your vehicle, always use a pH-neutral shampoo designed for ceramic coatings. Harsh or highly acidic/alkaline cleaners can break down the coating prematurely. I recommend Gtechniq’s GWash for a gentle, effective clean that pairs perfectly with your Crystal Serum coating. Alternatively, Autoglym’s Pure Shampoo is also a great choice. Remember to use two buckets (one for clean water, one for rinse water) to avoid swirl marks.

3. Wash by Hand, Not by Machine

Avoid automatic car washes, as they can scratch the coating. Hand washing with a soft microfiber wash mitt is the safest method. Work in straight lines rather than circles to minimise swirl marks.

4. Dry Gently

Use a soft, clean microfiber drying towel to dry your vehicle after washing. Pat dry rather than wiping to reduce friction and preserve the coating’s slick surface.

5. Use a Silica Spray Sealant

Every 2–3 months, refresh the hydrophobic (water-repelling) properties of your ceramic coating by applying a silica-based spray sealant. I recommend Gtechniq’s C2 Ceramic Sealant for the best compatibility and performance. Other high-quality options like Autoglym’s Rapid Ceramic Sealant can also work well. This extra layer of protection helps maintain that just-coated shine and boosts the longevity of your ceramic coating.

6. Avoid Harsh Chemicals and Polishes

Avoid using strong chemicals, abrasive polishes, or clay bars on your coated paintwork. These can strip away the ceramic layer, reducing its effectiveness.

7. Remove Contaminants Promptly

If you notice bird droppings, tree sap, or bug splatters on your vehicle, remove them as soon as possible with a gentle detailer spray and a microfiber cloth. These contaminants can etch into the coating if left too long.

8. Schedule Annual Inspections

For optimal longevity and to catch any early signs of wear, consider booking an annual inspection and top-up with me at Gavigan Detailing. This ensures your Crystal Serum ceramic coating continues to perform like new.

Conclusion:

Your Gtechniq Crystal Serum ceramic coating isn’t just a product—it’s an investment in your car’s beauty and protection.
