Top 10 Questions for Automotive Refinish Technician Interview

1. What are the different types of paint mixing systems used in automotive refinishing?

There are three main types of paint mixing systems used in automotive refinishing: gravimetric, volumetric, and spectrophotometric:

• Gravimetric systems measure the weight of the paint components to ensure accurate mixing ratios. This system is generally more expensive than other types of mixing systems but offers the highest level of precision.
• Volumetric systems measure the volume of the paint components to ensure accurate mixing ratios. This system is less expensive than gravimetric systems but may not offer the same level of precision.
• Spectrophotometric systems use a spectrophotometer to measure the color of the paint components and adjust the mixing ratios accordingly. This system is the most expensive type of mixing system but offers the highest level of color accuracy.

2. What are the different types of spray guns used in automotive refinishing?

Types of Spray Guns

• Conventional Spray Guns: These guns use compressed air to atomize the paint and propel it towards the surface being painted. They are less efficient than HVLP and LVLP guns but are less expensive and easier to maintain.
• HVLP (High Volume Low Pressure) Spray Guns: These guns use a high volume of air at a lower pressure to atomize the paint. They are more efficient than conventional spray guns and produce a finer finish.
• LVLP (Low Volume Low Pressure) Spray Guns: These guns use a lower volume of air at a lower pressure to atomize the paint. They are more efficient than HVLP guns and produce the finest finish.

Other Factors

• Gravity Feed vs. Suction Feed: Gravity feed spray guns are less expensive and easier to use, but they require more paint to be loaded into the gun.
• Nozzle Size: The nozzle size determines the width of the spray pattern. A larger nozzle size will produce a wider spray pattern, while a smaller nozzle size will produce a narrower spray pattern.
• Air Pressure: The air pressure determines the force with which the paint is atomized. A higher air pressure will produce a finer finish, but it can also cause the paint to dry too quickly.

3. What are the different types of primers used in automotive refinishing?

There are two main types of primers used in automotive refinishing: etch primers and surfacers:

• Etch primers are used to create a bond between the metal surface and the paint. They are typically applied to bare metal and are very thin.
• Surfacers are used to fill in surface imperfections and create a smooth surface for the topcoat. They are typically applied over etch primers and are thicker than etch primers.

4. What are the different types of clear coats used in automotive refinishing?

There are two main types of clear coats used in automotive refinishing: single-stage and two-stage:

• Single-stage clear coats are a one-step process that combines the color coat and the clear coat into a single product. This type of clear coat is less durable than two-stage clear coats but is easier to apply.
• Two-stage clear coats are a two-step process that involves applying a separate color coat and clear coat. This type of clear coat is more durable than single-stage clear coats but is more difficult to apply.

5. What are the different types of paint defects that can occur during automotive refinishing?

• Runs and sags occur when the paint is applied too thickly or the surface is not properly prepared.
• Orange peel is a rough, textured surface that can occur when the paint is not properly applied or the clear coat is not properly sanded.
• Fish eyes are small, round craters in the paint surface that can occur when there is contamination in the paint or the surface is not properly prepared.
• Blisters are raised areas in the paint surface that can occur when there is moisture or air trapped beneath the paint.
• Cracks are breaks in the paint surface that can occur when the paint is too brittle or the surface is not properly prepared.

6. What are the different types of tools and equipment used in automotive refinishing?

The following tools and equipment are commonly used in automotive refinishing:

• Sanding tools, such as sanders, sandpaper, and sanding blocks, are used to smooth and prepare the surface for painting.
• Masking tape and paper are used to protect areas of the vehicle that are not being painted.
• Spray guns are used to apply paint and clear coat to the vehicle.
• Mixing cups and sticks are used to mix paint and clear coat.
• Air compressors are used to provide air pressure for spray guns.
• Safety equipment, such as respirators, gloves, and eye protection, is essential for protecting the health and safety of the technician.

7. What are the different types of materials used in automotive refinishing?

The following materials are commonly used in automotive refinishing:

• Paints are used to provide color and protection to the vehicle.
• Clear coats are used to protect the paint and provide a glossy finish.
• Primers are used to create a bond between the metal surface and the paint.
• Masking tape and paper are used to protect areas of the vehicle that are not being painted.
• Sanding materials, such as sanders, sandpaper, and sanding blocks, are used to smooth and prepare the surface for painting.

8. What are the different types of techniques used in automotive refinishing?

The following techniques are commonly used in automotive refinishing:

• Spraying is the most common technique used to apply paint and clear coat to a vehicle.
• Rolling is a technique that can be used to apply paint or clear coat to small areas or to create special effects.
• Brushing is a technique that is typically used to apply touch-up paint or to create detailed designs.
• Sanding is a technique that is used to smooth and prepare the surface for painting, to remove imperfections from the paint surface, or to create special effects.
• Masking is a technique that is used to protect areas of the vehicle that are not being painted.

9. What are the different types of safety precautions that must be taken when working with automotive refinishing materials?

• Wear appropriate safety gear, such as respirators, gloves, and eye protection.
• Work in a well-ventilated area to avoid inhaling harmful fumes.
• Use proper lighting to ensure that you can see what you are doing.
• Keep all flammable materials away from open flames or sparks.
• Dispose of used materials properly to avoid contaminating the environment.

10. What are the different types of industry certifications that are available for automotive refinishing technicians?

The following industry certifications are available for automotive refinishing technicians:

• Automotive Refinish Technician (ART) certification from the National Institute for Automotive Service Excellence (ASE)
• Certified Automotive Refinish Technician (CART) certification from the Automotive Service Association (ASA)
• I-CAR certification from the Inter-Industry Conference on Auto Collision Repair (I-CAR)
