CD Paint Protection Film Installation 2 — Questions and Answers
Question 1: What is the recommended squeegee angle when smoothing PPF during installation to avoid lifting edges?
- 90 degrees to the surface
- 45 degrees to the surface
- 20–30 degrees to the surface (Correct answer)
- Parallel to the surface
Correct answer: 20–30 degrees to the surface
A 20–30 degree angle reduces the risk of edge lift while still channeling slip solution out effectively.
Question 2: Which type of PPF finish mimics a factory matte paint appearance?
- Gloss PPF
- Satin PPF
- Matte PPF (Correct answer)
- Carbon fiber PPF
Correct answer: Matte PPF
Matte PPF has a low-gloss surface texture specifically engineered to replicate matte factory finishes.
Question 3: What is 'orange peel' in the context of PPF installation?
- An adhesive contamination pattern
- A textured surface imperfection resembling citrus skin (Correct answer)
- An edge lifting defect
- A chemical staining reaction from slip solution
Correct answer: A textured surface imperfection resembling citrus skin
Orange peel describes a bumpy, textured surface appearance caused by uneven film stretching or improper heat application.
Question 4: When bulk cutting PPF on a plotter, what material is placed beneath the film to protect the cutting blade and mat?
- Release liner (Correct answer)
- Masking tape layer
- Silicone separator sheet
- Glass plate
Correct answer: Release liner
The release liner protects the cutting mat and keeps the adhesive covered until the film is ready to apply.
Question 5: Which area of a vehicle typically requires the most film stretching during a full-hood PPF installation?
- The flat center section
- The leading edge and curved corners (Correct answer)
- The cowl area near the windshield
- The hood hinges
Correct answer: The leading edge and curved corners
Leading edges and curved corners have compound curves that demand controlled film stretching to conform without wrinkles.
Question 6: What is a 'dry application' method of PPF installation?
- Applying film without any slip solution, relying on repositioning adhesive (Correct answer)
- Using only isopropyl alcohol as a lubricant
- Applying film over a dry paint surface without panel prep
- Heating the film before removing the liner
Correct answer: Applying film without any slip solution, relying on repositioning adhesive
Dry application uses no slip solution, relying on the film's repositionable adhesive for alignment before final commitment.
Question 7: After installing PPF, why should the vehicle be kept out of rain or automatic car washes for 48–72 hours?
- The film surface scratches easily when wet
- The adhesive needs time to fully cure and bond (Correct answer)
- Water causes the film to shrink
- The slip solution residue can stain paint if washed early
Correct answer: The adhesive needs time to fully cure and bond
The pressure-sensitive adhesive continues curing after installation and needs time to achieve full bond strength before exposure to water pressure.
