Automotive Refinishing

SOP - Clearcoat Finishing (Mar Resistant Repair)

• This identified process is for harder clearcoats such as EC530, G2-7779, HC-7776, DC2000
• Remove dirt nibs, runs or sags in clear coats
• Match original paint surface texture

Step 1 - Sand

Microstar® P2000

MRP-650CV Sander (6", 5mm orbit)
916SGV48 Backup Pad
1066F Interface Pad

Sand with 2000 grit (dry) using moderate speed. The clear should “powder” when sanding. If you cannot 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.

Step 2 - Finesse

Abralon® 4000

MR-650CV Sander (6", 5mm orbit)
916SGV48 Backup Pad

Refine sand scratches using 4000 grit Abralon® with a 50% overlap pattern (wet).

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.

To prevent water from entering tool, do not use vacuum system when wet sanding.

Step 3 - Buff

Polarshine® 10

MPADOF-8 Orange Foam Pad
(7" Rotary Buffer)

Buff using PC10 compound in conjunction with a orange foam pad (MPADOF-8).

Use a slow speed (1,500 rpm) to prevent “burning” the finish.

Keep the pad clean from compound build-up.

Step-4 Polish

Polarshine® 10

MPADBF-8 Black Foam Pad
(7" Rotary Buffer)

Polish using PC10 with a black foam pad (MPADBF-8).

Use a slow speed (1,500 rpm) to prevent “burning” the finish.
