What does block sanding aim to achieve?

Block sanding is primarily aimed at smoothing out surface irregularities. This technique utilizes a block to apply even pressure, allowing for a flat and uniform sanding action over large areas. By doing so, it helps to eliminate imperfections like waves, bumps, or uneven spots that may have occurred during previous stages of bodywork or painting.

The process not only prepares the surface for painting but also ensures that the final finish appears smooth and professional. Achieving this level of flatness is critical in producing a visually appealing and durable finish, as any retained imperfections can become accentuated once paint is applied. Additionally, block sanding can help bring out the contours of a vehicle, enhancing the overall aesthetic appeal.
