Why Do Bubbles Appear in Car Paint?

[LaHarrison]

Bubbles in car paint occur due to excessively high paint viscosity, applying too thick a coat at once, inadequate filling of pores trapping air, especially on porous substrates without a proper sealer primer; or from excessively high spraying air pressure introducing too much air into the paint. Below are relevant explanations: 1. Car Painting: Car painting refers to applying a layer of paint to the vehicle's surface to protect it. Automotive paint typically uses baking enamel. In car manufacturing plants, after the frame and body are welded, the next step is painting. Types include standard paint, metallic paint, and pearl paint. The painting process involves applying putty, sanding, and spraying. 2. Car Paint Types: Standard paint; metallic paint; pearl paint; clear coat; matte paint. Paint contains various solvents with benzene compounds like toluene and xylene. Thinners contain toxic industrial solvents like ethanol and butanol, some extremely hazardous such as methanol.
