BT-PH2B AC DA 21 mm Dual Action (D/A) Car Polisher

Using a 21mm Dual Action (D/A) polisher involves a series of steps to ensure effective paint correction, polishing, and finishing. The 21mm polisher, with its larger orbit size, is particularly suited for aggressive correction and covering large areas quickly. Here’s a step-by-step guide on how to use a 21mm D/A polisher effectively:

Preparation:

1. Clean the Surface:

- Thoroughly wash the car to remove dirt, debris, and contaminants. Clay the surface if needed to remove embedded particles.

- Dry the car completely to avoid water spots or streaks.

2. Choose the Right Pad and Compound:

- Pad Selection: Choose a pad appropriate for the task—cutting pads for heavy correction, polishing pads for moderate correction, and finishing pads for final polishing.

- Compound Selection: Select a compound suited to the level of defect you’re addressing. Use a cutting compound for significant defects, a polishing compound for light to moderate defects, and a finishing polish for the final stage.

3. Prep the Polisher:

- Attach the correct backing plate (usually 6 to 7 inches in diameter) to the polisher.

- Secure the polishing pad to the backing plate. Make sure it’s properly centered and attached.
