ABSTRACT:
A process for finishing a metal surface comprises subjecting the surface to successive grit blasting passes including a first series of successive blasting passes using an abrasive grit of a first diameter range applied with a blasting nozzle air pressure in a first range, and a second series of successive blasting passes using an abrasive grit of a second diameter range smaller than the first diameter range, applied with a blasting nozzle air pressure in a second range lower than the first range. Thereafter a third series of successive blasting passes, using glass grit of a third diameter range smaller than the second diameter range, is applied with a blasting nozzle air pressure in a third range lower than the first range.
