How To Use

2. Prime: Add 3–4 pea-sized drops; spread at speed 1–2 using the soft-start trigger.
3. Correct: Work a ~40 × 40 cm section with slow, overlapping passes; keep the pad flat with light, even pressure.
4. Inspect: Wipe residue; adjust pad/product as needed and continue.
5. 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.
