The verdict
The opening scuff or the closing one.
Maroon runs around 120-grit equivalent — aggressive enough to scuff old finish, lift light rust, and prep a surface for primer or stain. Gray runs around 600-grit, the last pass before a topcoat or the pre-polish on metal. They share a shape and a brand. They do completely different work.
Pick 3M if
Surface prep. Old finish has to come off; primer or stain is going on.
Pick 3M if
Between coats or pre-polish. The surface is already close to done.
