Absolutely. The Waxit Spray Coating Kit is completely safe for use on any surface that already has a ceramic coating or sealant applied. Both Nv LUSTRE and Nv JET were designed with flexibility in mind, meaning they can be used as stand-alone coatings or as maintenance layers to refresh existing protection. On a coated car, Lustre works to revive gloss, fill minor surface imperfections, and restore that smooth, “just-coated” slickness. It won’t interfere with the underlying coating; instead, it bonds lightly on top, reinforcing the hydrophobic layer and improving visual clarity.

Following with Nv Jet adds even more repellency and chemical resistance. Jet behaves almost like a self-cleaning topper, helping dirt and water slide off faster during washes. Together, they’re a simple way to extend the life of any paint protection or ceramic coating without needing full reapplication. Whether you’re maintaining a professional ceramic job or just keeping your weekend toy looking crisp, these spray coatings integrate seamlessly with any existing protection, making upkeep faster and safer than ever.

Durability depends on how and where the car is used, but both coatings in the Waxit Spray Coating Kit are built for real-world longevity. As a standalone ceramic spray coating, Nv Lustre can deliver up to six months of protection under regular driving and washing conditions. It resists UV, detergents, and environmental fallout, all while maintaining deep gloss and hydrophobic performance. When paired with Nv Jet, the top layer reinforces Lustre’s protection by adding a further two to three months of boosted slickness and chemical resistance.

That said, durability is heavily influenced by maintenance habits. Frequent washing with harsh soaps or letting contaminants bake on the surface can shorten protection, while using proper pH-neutral shampoos and gentle drying methods will extend it. Think of the system as modular Lustre provides the backbone, and Jet acts as the refresh layer that can be reapplied as often as you like. Used together, they offer a consistent, high-gloss finish and ongoing protection that’s far easier to maintain than traditional waxes or older-style sealants. In short, this car coating spray duo gives months of real, tangible defence against the elements without the fuss of full ceramic application.
