Paint protection film (PPF): maintenance, recommended products and best practices

Paint protection film ( PPF ) is an increasingly popular solution for protecting vehicle bodies from impacts, scratches, and everyday wear and tear. While highly durable, paint protection film still requires proper maintenance to preserve its transparency, gloss, and hydrophobic properties.

In this guide, you will understand:

• what is a PPF in French
  
• How to properly maintain a PPF
  
• which CARPRO products to use
  
• Mistakes to avoid , such as polishing on film
  
• Recommended protective products to improve shine and hydrophobicity

What is a PPF?

PPF (Paint Protection Film) translates into French as film de protection de peinture .

This is a transparent polyurethane film applied to the bodywork to protect the surface against:

• gravel impacts
  
• micro-scratches
  
• abrasion
  
• road contaminants
  
• insects and debris

Most modern films also possess self-healing properties. Some micro-marks disappear with heat.

The PPF therefore acts as a physical barrier between the environment and the original paint.

A new generation of PPF: Instant Self-Healing technology

Most traditional paint protection products (PPFs) require heat to activate their self-healing properties. Micro-scratches typically disappear when the surface is exposed to sunlight or hot water.

CARPRO has developed a different approach with its Immortal PPF range.

This technology uses Instant Self-Healing , capable of regenerating even at low temperatures , down to about -20°C .

This means that micro-marks can disappear without needing a significant heat source , which is a major advantage in cold climates like Canada.

Other important features:

• reinforced surface with integrated nano-ceramic
  
• very high luster
  
• advanced hydrophobia
  
• Increased resistance to contaminants

This combination results in a film that effectively protects the paintwork while maintaining a very glossy and easy-to-maintain appearance .

How to properly maintain a PPF

A PPF is maintained almost like a paint , but with certain precautions.

A simple and secure protocol includes:

Washing

• pre-wash foam or alkaline (e.g. CARPRO Lift )
  
• High-pressure rinsing
  
• Hand washing with pH-neutral shampoo (e.g., CARPRO Reset )
  
• drying with quality microfibers

The goal is simple: reduce friction and avoid abrasive contaminants .

Aggressive or improper washing can dull the film over time.

Decontamination

Over the years, a PPF can accumulate:

• ferrous contaminants
  
• tar
  
• road debris

Useful products:

• CARPRO IronX – Ferrous Contaminants
  
• CARPRO TarX – tar

Occasional decontamination helps to maintain the transparency and hydrophobicity of the film .

What not to do on a PPF

Certain practices should be avoided.

Avoid polishing

Polishing on PPF is strongly discouraged .

Unlike varnish, the film has a limited thickness .
Polishing a film can:

• thin the protective layer
  
• alter the self-healing properties
  
• create an irregular finish

In some very specific professional cases, a slight correction may be possible, but this is generally not recommended for standard maintenance .

Avoid harsh products

Some strong solvents or industrial cleaners can damage the film or affect adhesion .

It is best to use products that are compatible with screen protectors .

Recommended protections for a PPF

Adding protection improves:

• the chandelier
  
• hydrophobia
  
• ease of washing

CARPRO offers several options adapted to paint protection films .

CARPRO C.Quartz Skin

C.Quartz Skin is a protective product specifically developed for:

• PPF
  
• vinyl
  
• wrap

Features :

• improves shine
  
• increases hydrophobicity
  
• facilitates maintenance

Unlike many coatings, Skin is not semi-permanent .
It can therefore be used on:

• matte films
  
• matte vinyls
  
• surfaces that are difficult to correct

Since a matte surface cannot be polished , it is best to use an easily removable protective coating, which makes Skin particularly interesting.

CARPRO DLight

C.Quartz DLight is a much more sustainable solution.

It can be considered the "on steroids" version for protection:

• PPF
  
• wrap
  
• plastics
  
• matte paint

Benefits :

• excellent durability
  
• strong UV protection
  
• High hydrophobicity

However, DLight is semi-permanent .

On a matte surface, this means that you need to be certain of the application, since the correction is much more complex.

Key points to remember

PPF stands for paint protection film

• It protects the bodywork against impacts and abrasions.
  
• The new generation, such as CARPRO Immortal PPF, offers Instant Self-Healing down to -20°C.
  
• Some films incorporate a nano-ceramic structure that improves luster and hydrophobicity
  
• Maintenance relies on gentle and regular washing.
  
• Avoid polishing on the protective film
  
• Protective products like C.Quartz Skin enhance shine and hydrophobicity
  
• C.Quartz DLight offers more durable but semi-permanent protection
  
• Matte surfaces require a cautious approach.

FAQ

Does a PPF need to be maintained?

Yes. Even though the film protects the paint, it accumulates contaminants. Regular maintenance helps preserve its transparency and performance.

Can a coating be applied to a PPF?

Yes. Several screen protectors are designed specifically for films, such as C.Quartz Skin or C.Quartz DLight .

Can a PPF be polished?

This is generally not recommended. The film has a limited thickness and polishing can damage it.

Can matte films be protected?

Yes, but you have to use compatible products. Non-permanent protectors like C.Quartz Skin are often preferred.
