What methods do both Technicians A and B use after filling and leveling a ding?

After filling and leveling a ding, both Technicians A and B utilize effective sanding methods to ensure a smooth finish on the repaired surface. The dual action sander is valuable for achieving a fine finish on larger areas, allowing for efficient sanding without creating grooves or uneven surfaces. It operates in a circular motion while also oscillating, providing a smooth sanding action that is suitable for bodywork.

The block sander, on the other hand, is ideal for smaller, more confined areas. This tool allows for stable and controlled sanding, which is crucial for getting into tighter spots around the repair without damaging the surrounding paint or bodywork. By using the block sander, technicians can maintain even pressure to create a flat and uniform surface.

By incorporating both methods, technicians can take advantage of the strengths of each tool — the efficiency of the dual action sander for broader areas and the precision of the block sander for detailed work. This comprehensive approach ensures that the ding is not only filled and leveled adequately but finished to a high standard, promoting better adhesion of primer and paint for a seamless repair.
