After filling and leveling a ding, who correctly uses a tool to featheredge paint edges?

Feathering paint edges is an important part of preparing a surface for repainting, as it helps to create a smooth transition between the new paint and the existing paint. Both technicians utilize appropriate tools for this task, which makes their approaches valid.

A dual action sander is particularly effective for feathering because it combines both rotary and oscillating motions, allowing for efficient material removal while minimizing the risk of damaging the surrounding area. This type of sander is ideal for getting into tighter spaces and can produce a very smooth finish if used properly.

On the other hand, a block sander is also appropriate for feathering edges, particularly when dealing with larger flat areas. The flat surface of the block sander allows for even pressure distribution and helps create a level finish that blends the old paint with the new.

Both techniques are effective in feathering paint edges, making it crucial that the technician selects the right tool based on the specific circumstances of the repair. Hence, both technicians are correctly employing their tools to achieve a quality finish.
