ME? Depends on the scratch depth, the RMS finish required, and the surety that all lapping compound is removed.
Controlling depth without proper equipment (most don't have it) that is exactly perpendicular to surface and contact is equal all around is critical.
At Mercury Marine we roller burnished round shafts. It crushed the high points and sealed "pores" in the metal by crushing high points into valleys, such that the surface was quite smooth--sometimes a 10 RMS and also helped deter rust.
