Achieve optimal correction and clarity by following these simple steps: PREPARATION Work in a cool, well-lit, and clean environment. Wash the surface using FEYNLAB® PURE WASH or PURE RINSELESS. Clay bar the paint to remove bonded contaminants. MACHINE SETUP Use a dual-action (DA) or rotary polisher. Shake the bottle well for 1 minute before use. Prime the pad with 4 dime-sized dots of A500. APPLICATION Apply 4 additional dots on the panel. Work in small sections (approx. 2 ft x 2 ft). Polish using medium-to-high speed, making 2–4 slow passes until the product turns clear. Wipe off residue immediately with a clean microfiber towel. BETWEEN SECTIONS Clean the pad using compressed air or a brush. Reapply A500 as needed. Inspect the surface from multiple angles to confirm defect removal. FOR BETTER RESULTS For deeper defects, start with FEYNLAB® A50 before A500. To refine gloss and clarity, finish with FEYNLAB® A1000. If residue sticks, lightly mist the panel with water before wiping.
