Polishing
Polishing is done in two steps: The first step is with an 8" buffer and the second step with a dual action sander to remove buffing and swirl marks. Low speed (1500-1750 RPM) is necessary to prevent over-heating the surface.CAUTION:
Do not polish or buff a surface dry. More than the usual quantity of liquid must be used to keep the paint surface cool. Wipe the excess material off with a clean soft towel after each operation.
1. Clean the surface of all residue before polishing.
2. Use an 8" buffer (at 1500-1750 RPM) with either a 3M wool polishing pad or a Meguiar's foam pad, apply polishing compound over the work area (2' x 2' or less). Spread the liquid around with the pad before turning the buffer "ON". Use an overlapping pattern to assure even polishing effort on all areas.
3. Second use a dual action sander with either a 3M foam pad or a Meguiar's foam pad, apply polishing liquid over the work area (2' x 2' or less). Polish with the same technique as above. Do not polish dry. Wipe off excess material with a clean terry cloth towel.
If build up occurs, cool the surface with clean water and dry with a clean terry cloth towel and clean the foam pad. Use a slower speed to prevent heating the surface and ground the vehicle to a metal water pipe to reduce static electricity.
INSPECTION
Gently clean a small section of the surface with PPG DX330 Wax and Grease remover or similar wax remover, using a clean towel to remove any polish/filler. Wipe in one direction to aid in distinguishing between buffing scratches and towel scratches. Inspect the surface for swirl marks under full sunlight or with a 500 watt halogen work lamp held at an angle about an arms length away.
CAUTION:
If you clean with an alcohol and water cleaning solution it will cause damage to plastic lenses. The damage is not immediately visible, but develops later.
