How to Remove the Grainy Feel in Paint?
2 Answers
Methods to remove the grainy feel in paint: 1. Clean and wipe the surface of the car body thoroughly; 2. Use a polishing machine with polishing powder for polishing; 3. Apply wax to the car. The grainy and uneven paint may be due to an unleveled base layer, too thin a paint layer, poor construction environment causing dust to fall during spraying, or inappropriate paint viscosity leading to poor spraying results. It is advisable to develop a habit of regular maintenance and pay attention to paint care. Some paint maintenance projects, such as waxing, glaze sealing, coating, and crystal coating, can protect the car paint to a certain extent.
I've been painting cars myself for many years and have encountered the issue of orange peel texture numerous times. It's mainly caused by dust or impurities floating into the paint during application, or spraying paint that hasn't been properly mixed. Here's how to fix it: First, lightly wet sand the surface with 2000-3000 grit sandpaper, being careful not to sand through the paint layer (otherwise you'll need to repaint). Then use an electric polisher with coarse compound to level the surface, followed by fine compound for smoothness. Finally, apply protective wax to prevent oxidation. Always use quality tools - for instance, a rotary polisher helps avoid swirl marks. For prevention, I always paint in a sealed, clean environment, maintain about 20cm spray gun distance, and preheat the paint to reduce fast drying. Safety first - always wear a dust mask. These methods have saved me considerable money through trial and error, but beginners should take it step by step.
