Paint protection can be useful on both new and used vehicles, but a used car needs a more detailed assessment first.

AVP checks contamination, wash marks, oxidation and signs of previous repair. Paint-thickness readings can support the decision on compatible panels, although they do not replace visual inspection or reveal every underlying layer.

The finish is then washed and decontaminated. Polishing is carried out only where correction is useful and the available paint allows it; not every used car needs an intensive process.

Wax, sealant or ceramic protection can preserve the prepared appearance and make maintenance easier. It does not create a self-cleaning surface, prevent all UV ageing or make bird residue safe to wipe away without proper washing.

Before resale, careful preparation can improve presentation and buyer confidence, but no treatment guarantees a fixed increase in value.

AVP recommends the scope after seeing the vehicle rather than applying an old price or durability promise.
