Microstar 800 + 1500
FM-611-800, -1500

MID65020CAUS Sander 
916GV48 Backup Pad
1066F Interface Pad

Level orange peel and any defects using an electric DEROS or pneumatic PROS sander with Microstar® P800. Follow with P1500 grit (dry) using moderate speed. The coating should "powder" when sanding. If you can not produce dust, then it is not dry enough to sand. Sanding too early risks producing "pills" which will damage the surface.

FM-612-1500

MR-5 Sander
915GV28 Backup Pad
9155-5 Interface Pad

Follow with 1500 grit (dry) using moderate speed.

The coating should “powder” when sanding. If you can not produce dust, then it is not dry enough to sand. Sanding too early risks producing “pills” which will damage the surface.

Microstar was designed to remove runs, dust nibs, excess orange peel or other surface defects in painted surfaces or gelcoat prior to polishing.

MID65020CAUS Sander 
916GV48 Backup Pad

Refine sand scratches with Abralon® 3000 grit with a 50% overlap pattern
(damp). Spray the pad and surface with clean water. If too much is used, it will be evident by water "slinging" from the pad, and the abrasive will float over the surface with reduced cutting action.
