How can you identify filler in a repaired area?

• A. By checking for glossy paint
• B. Through sanding and inspecting for inconsistencies in surface texture
• C. By using a magnet on the surface
• D. By measuring the thickness of the paint

Answer: (B)

Identifying filler in a repaired area is effectively done through sanding and inspecting for inconsistencies in surface texture. This method allows the technician to feel for variations and detect any discrepancies beneath the paint surface. Filler is often used to smooth out dents and imperfections; thus, when you sand the area, you may notice a difference in texture compared to the surrounding metal. Filler typically presents a softer consistency than the underlying material, revealing itself through irregularities such as waves or an unnatural smoothness.

Other options may not provide reliable identification of filler. Glossy paint can be a sign of various paint finishes and doesn't specifically indicate the presence of filler. Using a magnet is great for detecting metal, but it would not inform you about filler materials, which may not be magnetic. Measuring paint thickness might hint at repairs, but it won't necessarily confirm the presence of filler without additional texture assessment. Therefore, the sand-and-inspect method stands out as the most effective way to identify filler in auto body repairs.
