How to choose a paint protection shop: 8 questions to ask before installation

The best film or coating on the market can give a poor result if the installation is weak. Choosing the shop matters as much as choosing the product. Ask these questions before you decide.

1. What is the product, and who makes it?

Ask for the exact name of the film or coating, not a general description such as "American film" or "German ceramic". That lets you check the product and its specifications.

2. How long is the warranty, and what does it cover?

• Ask for the warranty in writing.
• Ask which problems are covered: yellowing, cracking, peeling, staining, bubbling.
• Ask: is the warranty registered with the manufacturer? Some manufacturers only honour a warranty if the shop is authorised by them.

3. Is the shop authorised by the manufacturer?

Authorisation usually means the installers were trained on the product and the warranty is official. Ask for proof.

4. (PPF) Are the panels computer-cut or hand-cut?

• Computer-cut (pattern): ready-made pieces designed for your car model, giving a consistent, precise result.
• Hand-cut (bulk): the film is cut on the car itself, which takes a lot of skill.

Both methods can give an excellent result. What matters is the installer's experience, so ask what they recommend for your car specifically.

5. (PPF) Are the edges wrapped?

Wrapping the film around the edges of a panel makes the cut lines less visible and reduces the chance of edges lifting over time. Ask which panels will have wrapped edges.

6. (Ceramic) Does the price include paint correction?

A ceramic coating locks in whatever is underneath. Ask: will you polish the paint before applying it? In how many stages? And is that included or extra?

7. How long will you keep the car, and when can I wash it?

A good installation takes time, so be wary of a very fast turnaround. Ask how long to wait before the first wash and for the aftercare instructions.

8. Can I see previous work?

Ask to see a car at the shop, or close-up photos of real work, especially edges and corners.

Warning signs

• A price far below the market with no clear explanation.
• Refusing to name the product or give a written warranty.
• Exaggerated promises, such as "ceramic that stops every scratch".
