IDA Paint Protection and Coatings 2 — Questions and Answers
Question 1: What is the 'beading' property of a ceramic-coated surface?
- The surface develops small bumps from the coating
- Water forms tight, round beads that roll off the surface due to the hydrophobic properties of the coating (Correct answer)
- Wax pearls are embedded in the coating layer
- Air bubbles form under the coating during application
Correct answer: Water forms tight, round beads that roll off the surface due to the hydrophobic properties of the coating
Beading is the hydrophobic property of a ceramic coating that causes water to form tight, round droplets that roll off the surface rather than spreading or sheeting.
Question 2: Which panel preparation step is critical before PPF installation to ensure proper film adhesion?
- Applying a base layer of wax first
- Thoroughly cleaning and decontaminating the paint surface and removing all oils and residues (Correct answer)
- Sanding the paint surface lightly
- Applying a chemical etch primer to the paint
Correct answer: Thoroughly cleaning and decontaminating the paint surface and removing all oils and residues
The paint surface must be completely clean and free of waxes, oils, clay residues, and contaminants so the PPF adhesive can bond securely to the paint.
Question 3: What is the function of an 'installation gel' or 'slip solution' when applying PPF?
- It activates the PPF adhesive so it bonds faster
- It allows the film to be repositioned on the panel before final squeegee installation (Correct answer)
- It seals the edges of PPF permanently
- It prevents PPF from yellowing over time
Correct answer: It allows the film to be repositioned on the panel before final squeegee installation
Slip solution (usually diluted baby shampoo in water) prevents the adhesive from bonding immediately, giving the installer time to position the film correctly before squeegeeing it down.
Question 4: What is a common cause of ceramic coating 'high spots' after application?
- Using too little product during application
- Failing to level the coating with a microfiber cloth within the flash time window (Correct answer)
- Applying the coating in cold temperatures
- Using a foam applicator instead of a suede applicator
Correct answer: Failing to level the coating with a microfiber cloth within the flash time window
High spots occur when a ceramic coating is not leveled within its flash time, causing uneven curing that creates visible streaks or spots that are very difficult to remove.
Question 5: Why is panel temperature checked before applying a ceramic coating?
- Hot panels cure the coating too slowly
- Panels that are too hot cause the coating to flash too quickly, reducing working time and causing high spots (Correct answer)
- Cold panels cause the coating to run off
- Panel temperature has no effect on coating application
Correct answer: Panels that are too hot cause the coating to flash too quickly, reducing working time and causing high spots
High panel temperatures dramatically reduce flash time, causing the coating to harden before it can be properly leveled, which leads to high spots and uneven protection.
Question 6: What is the main advantage of a professional-grade ceramic coating over a consumer-grade product?
- Consumer coatings are always brighter
- Professional coatings contain higher SiO2 concentrations and require professional surface prep for stronger, longer-lasting bonds (Correct answer)
- Consumer coatings are more durable in all conditions
- Professional coatings are only available in black
Correct answer: Professional coatings contain higher SiO2 concentrations and require professional surface prep for stronger, longer-lasting bonds
Professional ceramic coatings typically have higher SiO2 content and require thorough surface preparation, resulting in harder, more durable protection that outlasts consumer options.
