When wet sanding a hood, roof, or deck lid, how should the sanding be performed?

• A. across the length of the hood
• B. across the width of the hood
• C. in circular motions
• D. diagonally

Answer: (A)

Long, straight strokes along the length of the panel. This direction creates a uniform, easy-to-blend scratch pattern and lines up with the panel’s natural run lines, making sanding marks less visible once you finish and apply primer and paint. Movements across the width, in circular, or diagonal patterns tend to leave cross scratches or swirls that are harder to blend and can show through the final finish. Keep the surface wet, use light, even pressure, and overlap slightly with each pass for a smooth, consistent result.
