How to Deal with Rough Surface After DIY Painting?
2 Answers
To address a rough surface after DIY painting, the solution is to repaint or brush paint again. Relevant information is as follows: 1. Introduction: Painting is a simple and commonly used surface treatment process. It involves placing paint into a container, pressurizing it with machinery, and then spraying the paint in a mist form onto the product to form a paint film. Painting is widely used in fields such as ships, locomotives, bridges, and machinery. 2. Function: The main purpose of painting is to protect products or semi-finished products from rust and corrosion, while also serving a decorative role to enhance the product's appearance.
I also encountered a sandpaper-like paint surface when repainting my motorcycle before. Never rush to apply new paint directly! First, use 2000-grit wet sandpaper with soapy water to gently sand the rough areas—keep your hand steady. Sand until it feels smooth but without exposing the primer, or all your effort will be wasted. After drying, use polishing wax with a wool pad at low speed—an old sewing machine's flywheel can work as a makeshift turntable. Finally, apply three thin coats of blending lacquer to feather the edges, waiting 20 minutes between each coat. The matte finish achieved this way often looks even better than the factory paint. The key is patience—last time, I spent an entire afternoon sanding my instrument cover, and the result surpassed even professional auto shops.
