Is Polishing Required After Applying Automotive Gloss Clear Coat?
2 Answers
Polishing is not required after applying automotive gloss clear coat. The gloss clear coat is typically applied after car washing to serve a maintenance purpose. When a car undergoes touch-up painting, color discrepancies may appear between the repainted area and the original paint. In such cases, blending clear coat is used around the repainted area to create a transition, aiming to eliminate visual color differences. Below is an introduction to gloss clear coat: 1. Definition of Gloss Clear Coat: Essentially, gloss clear coat is a photosensitive resin with high gloss brightness used for protecting the car body surface or improving its glossiness. 2. Methods for Removing Gloss Clear Coat: Dissolving with weak acid and warm water, dissolving with high-purity ethanol, dissolving with glycerol (propane-1,2,3-triol), dissolving with butyl acetate, etc.
As an auto restoration enthusiast, sanding after spraying gloss clear coat is a must. It removes dust or orange peel left from painting, restoring a smooth, like-new surface. The process is simple: first lightly sand with 1500-2000 grit sandpaper, then rinse and polish to restore shine. Without sanding, the paint will quickly oxidize yellow or get scratched—not just unsightly but also shortening the protective layer's lifespan. I recommend treating it right after spraying; combining with waxing yields better results. This step takes little time but offers great returns, avoiding costly major repairs. Long-term, maintaining paint aesthetics also boosts resale value.
