Which of the following are removed when using heating techniques?

• A. Rust on exterior panels
• B. Dents in padded interior parts
• C. Cracks in laminated glass
• D. Hail damage on roof

Answer: (B)

Heating techniques rely on softening pliable interior materials so a dent can be reshaped or pushed back toward its original contour. When you apply heat to padded interior parts—like vinyl or foam-backed trim—the material becomes more pliable, allowing the dented area to be reformed cleanly without tearing or leaving a ripple. This is why dents in padded interior parts are the ones addressed by heating methods.

Rust on exterior panels is a corrosion issue that requires rust removal or treatment, not simply heating. Cracks in laminated glass are structural damage that heat can worsen, so they’re not repaired by heating. Hail damage on the roof creates dents in exterior metal, which is typically handled with mechanical dent repair methods or replacement rather than heating interior padding techniques.
