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.
Microstar® P1500
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.
Abralon® 3000
8A-241-3000
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.

Buff using either a MR-30 Palm Buffer or ARP300-B Cordless Polisher and PC10 compound in conjunction with a twisted wool pad (MPADTW-7.5-1.25) Use a slow speed (1,500 rpm) to prevent "burning" the finish. Keep the pad clean from compound build-up. (If unable to use twisted wool, you can substitute a lambs wool pad MPADLW-7.5)
Finishing Compound

(7” Rotary Buffer)
Polish using either a MR-30 Palm Buffer or ARP300-B Cordless Polisher and Polarshine® VF5 (FC5-1L) compound with a black foam pad (MPADBF-8). Use a slow speed (1,500 rpm) to prevent "burning" the finish. Wipe surface clean using a lint-free microfiber cloth (M-9915G).
