What can be done to avoid rough finishes at the end of a spray stroke?

To achieve a smooth finish at the end of a spray stroke, avoiding arcing the gun is crucial. Arcing refers to the action of moving the spray gun in a way that causes the spray pattern to change direction or create uneven coverage. When the gun is arced, the paint may not evenly distribute, resulting in rough or uneven surfaces. Maintaining a consistent angle and distance while keeping the gun level helps to create a uniform finish.

In contrast, keeping the gun steady is beneficial but may not specifically address the issue of arcing. Similarly, avoiding releasing the trigger or spraying from a closer distance can lead to other problems such as runs or drips in the paint, rather than ensuring a smooth spray pattern. Avoiding arcing ensures that the spray is directed consistently and evenly across the surface being painted, which is key to avoiding rough finishes.
