Sun, salt and calima: why paintwork ages faster on the Alicante coast

A car that lives inland and one that spends its life between Granja de Rocamora and the coast will age differently. Here, the main challenges are not cold or snow but strong sunlight, airborne salt and calima dust. All three can affect the paint system, including the clear coat, which helps protect the colour and gloss.

What actually happens to the clear coat

Clear coat is transparent and contains UV protection, but its performance can deteriorate over time. Sunlight, heat and other environmental factors gradually affect the finish, which may lose elasticity, become matt and eventually start to flake. That is why wear often shows first on the roof, bonnet and the top of the tailgate: the horizontal surfaces exposed to the midday sun.

If the clear coat starts to lift, the underlying colour is exposed and polishing is unlikely to solve the problem. Repainting the panel may be necessary, but the condition should be assessed first. Prevention is inexpensive; once the finish has seriously deteriorated, professional bodywork and paintwork may be required.

The salt does not have to come from the beach

You do not need to park on the seafront. Depending on the weather and local conditions, sea spray and airborne salt can travel inland and settle on the car, particularly when combined with overnight humidity. It can affect areas such as the underside, fasteners, brake lines and the lower edges of the doors and tailgate.

If the car has been to the beach, rinsing it with fresh water as soon as possible, including the underside, helps remove salt deposits and reduce the risk of corrosion. It cannot guarantee a particular lifespan, but it is a useful habit.

The calima

Calima leaves a film of fine dust that may contain hard particles. A common mistake is wiping it with a dry cloth, which can drag the dust across the paintwork and cause scratches. The circular marks often seen on dark cars in bright light can be caused by this.

After calima: use plenty of water first so the dust can be rinsed away, and only then use a microfibre mitt.

A routine that works here

• Wash every two or three weeks, always in the shade and when the car is cool.
• Use two buckets: one with car shampoo and one with plain water for rinsing the mitt. This helps prevent the same grit being dragged around the paintwork.
• Dry with a microfibre cloth; do not let the water dry naturally, as the local hard water can leave marks that are difficult to remove.
• Apply wax or sealant every three or four months. This sacrificial layer takes some of the punishment instead of the clear coat.
• Remove bird droppings and insect remains as soon as possible, as they can mark the clear coat, particularly in summer.
• If the car is parked outside all year, consider a ceramic coating. Depending on the product, preparation and maintenance, it may last considerably longer than wax and make the car easier to clean.

When polishing helps and when it does not

If the gloss has faded but the surface is still smooth and even, polishing may improve its appearance before applying a protective sealant. If you can see whitish patches, lifting edges or matt areas up close, this may indicate significant clear-coat degradation. Polishing could make the damage worse, so the surface should be assessed before any work is carried out.

In the workshop, we inspect the car when it is dry and in good light, then advise whether polishing or paintwork is the more suitable option. There is no sense charging you for polishing a car that needs paint, or painting a panel that two hours of machine polishing could still improve.
