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. .dtl-compare-3col .table-wrap{overflow-x:auto;-webkit-overflow-scrolling:touch} .dtl-compare-3col table{width:100%;border-collapse:collapse} .dtl-compare-3col caption{text-align:left;font-weight:700;margin:0 0 .5rem} .dtl-compare-3col th,.dtl-compare-3col td{border:1px solid #e5e7eb;padding:.75rem;vertical-align:top} .dtl-compare-3col thead th{background:#f9fafb} .dtl-compare-3col th[scope="row"]{width:28%;min-width:220px} /* Keep the feature column visible while horizontally scrolling on small screens */ @media (max-width:900px){ .dtl-compare-3col thead th:first-child{position:sticky;left:0;z-index:2} .dtl-compare-3col th[scope="row"]{position:sticky;left:0;background:#fff;z-index:1} } 21mm vs 15mm Long-Throw DA Polishers 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.
