BT-PH21B 21mm Dual Action D/A Polisher For Car Paint Care
PRODUCT descriptiion
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.
Polishing Process
1. Apply the Compound:
- Apply a few small drops of compound to the center of the pad. Avoid over-applying, as a little goes a long way.
- Spread the compound on the surface manually before turning on the polisher to prevent splattering.
2. Set the Polisher Speed:
- Start with a lower speed setting (around 2 to 3 on a scale of 6) to spread the compound evenly across the surface.
- Increase the speed (up to 5 or 6) for more aggressive cutting or polishing. The exact speed will depend on the level of correction needed and the type of compound used.
3. Polish the Surface:
- Positioning: Place the polisher on the surface before turning it on to avoid sudden contact that could damage the paint.
- Movement: Use overlapping passes, working in small sections (2x2 feet is a common size). Move the polisher in straight lines or overlapping passes, and keep it moving to avoid burning the paint.
- Pressure: Apply moderate to firm pressure, depending on the task. Avoid excessive pressure, as the polisher’s weight and pad rotation should provide sufficient cutting action.
- Technique: Work in a crisscross pattern to ensure even coverage and prevent holograms or swirl marks.
4. Check Your Work:
- Periodically wipe off the residue with a clean microfiber towel to inspect your progress. Check for defects and ensure that the surface is being corrected evenly.
- If needed, adjust your technique, pad, or compound to address any remaining defects.
5. Final Polishing:
- Once you’ve achieved the desired level of correction, switch to a finer polish or finishing pad.
- Use a lower speed setting and apply a finishing polish to enhance gloss and clarity.
- Again, work in overlapping passes and use light pressure.
6. Clean Up:
- After polishing, thoroughly clean the surface to remove any residual compound or polish.
- Inspect the finish to ensure all defects have been addressed and that the surface is glossy and smooth.
Safety and Maintenance
1. Wear Safety Gear:
- Use safety goggles and a dust mask to protect yourself from dust and compound splatter.
- Ensure proper ventilation in your workspace to avoid inhaling any fumes.
2. Maintenance:
- Clean the pads regularly during use to remove residue and prevent clogging. Use a pad cleaning brush or pad washer.
- Inspect the polisher and pads for wear and replace them as needed to maintain performance.
Summary
Using a 21mm D/A polisher involves selecting the appropriate pad and compound, applying the product correctly, and using proper technique to achieve effective paint correction and a high-gloss finish. The 21mm throw provides aggressive cutting power and efficiency for large areas and significant defect removal, making it a valuable tool for both professional detailers and automotive enthusiasts. Always follow proper procedures and safety guidelines to ensure the best results and maintain the condition of your vehicle’s paint.
