What Causes Bubbles in Car Touch-Up Paint?

[VanSilas]

The reasons for bubbles in car touch-up paint include poor paint quality, inadequate construction conditions and processes, and uneven paint application. Here are some precautions for quick repairs: Primer: The base material must be completely dry before applying the clear coat; otherwise, the paint surface may lose its gloss. Base coat: Single-component base coat must be used for quick repairs. Clear coat: The spraying pressure should not be too high (2-2.5 KPa). The standing time between each coat is 1-2 minutes, depending on the surrounding temperature during spraying. The lower the temperature, the longer the standing time, and vice versa. The spraying thickness should be 1.5-2 cm, not too thick, otherwise it will not dry easily. After applying the clear coat, it must stand for 5 minutes before baking. Sanding: Use P1500-P2000 beauty sandpaper to sand dust spots and sand the entire area to a matte finish (dry sanding equipment is recommended; if wet sanding is used, rinse more to prevent scratches from embedded grit). Lightly sand the interface areas. Polishing: Use polishing compound.
