What this means is that most new paint jobs don't actually require paint protection, but that doesn't mean that your car's brightwork can't benefit from some extra defence.
When it comes to your options for a protective coating you have 4 to choose from. A plastic adhesive film, a vinyl wrap, a ceramic coating, or graphene coating.
If you have an older car with scratched or faded paintwork applying a paint protection system may be a lost cause unless you do a paint rejuvenation or correction
The biggest consideration here is what kind of environment your new car will find itself in on a daily basis and if that is an aggressive environment you may want to consider one of the above paint protection systems.
