How To Use
- Plate & pad: Verify the installed 6" DA plate; center a clean, appropriate pad.
- Prime: Add 3–4 pea-sized drops; spread at speed 1–2 using the soft-start trigger.
- Correct: Work a ~40 × 40 cm section with slow, overlapping passes; keep the pad flat with light, even pressure.
- Inspect: Wipe residue; adjust pad/product as needed and continue.
- Finish: Switch to a finishing pad and fine polish for maximum gloss and clarity.
Notes: Clean or swap pads often to manage heat and maintain cut/finish. Avoid heavy edge pressure on body lines. Use on cool panels, out of direct sun.
| Feature | 21 mm Long-Throw DA Polisher | 15 mm Long-Throw DA Polisher |
|---|---|---|
| Orbit Size (Throw) | Larger (21 mm) | Standard (15 mm) |
| Correction Speed | Fastest. Covers more area per rotation for quicker defect removal. | Fast/Balanced. Highly effective; a bit less coverage per pass than 21 mm. |
| Ideal Panels | Large, flat surfaces (hoods, roofs, doors, large SUVs, trucks, boats). | All-around use, especially small to medium panels. |
| Maneuverability | Lower. More prone to pad stalling on heavy curves/concave areas; trickier near edges. | High. Excellent around body lines, pillars, bumpers with fewer stalls. |
| Standard Pad Size | Typically a 6-inch pad. | Typically a 5-inch pad. |
| User Fatigue | Can generate slightly more vibration due to the larger motion. | Generally smoother operation for longer sessions. |
