Mark's above post beat my "OMG, no!" thought just a few minutes ago reading the Op's last reply. If ever there was a time for actual hand work it is when paint prepping. Especially when close to masked or plated surfaces. 120 grit cloth folded around a half round file can do a fine job following lug edges. Remember the goal at this stage is etching the surface and not removing any real material. Power tools are best left to the fabrication stages. Andy
