When photographing polished metal, reducing flash power makes a distracting reflection darker, but does not move it. Its position depends on the relationship between the light source, the product surface and the camera.

Start with a fixed camera position and move one light at a time. Watch how the reflection travels across the product before adjusting exposure. On curved objects, different sections can reflect different parts of the studio.

How do you usually control unwanted softbox reflections on curved metal?
