Welcome to the "Automotive Painting Problems Identification and Correction" page!
This guide is designed to help you identify the most common automotive painting errors and provide practical solutions for correction. Whether you are an experienced automotive painter or a beginner, this guide will help you understand the problems that arise during the painting process and find the best ways to fix them.
Runoff
Paint does not adhere evenly, leading to drips, drops, or the entire layer of paint sliding.
Causes and Correction >>
Blushing ("Haze")
Blushing primarily occurs when painting in humid conditions. The air from the spray gun and the evaporation of the solvent lower the substrate's temperature below the dew point, causing moisture to condense on or within the paint.
Causes and Correction >>
Pinholes
Small pits the size of a needle head or leather-like pores appear on the surface from top to bottom.
Causes and Correction >>
Solvent Popping
Small bubbles form in the paint layer, which may burst. This often occurs on humid or hot days when moisture gets into the paint.
Causes and Correction >>
Loss of Gloss
Blushing primarily occurs when painting in humid conditions. The air from the spray gun and the evaporation of the solvent lower the substrate's temperature below the dew point, causing moisture to condense on or within the paint.
Causes and Correction >>
Solvent Aggression
The topcoat lifts the underlying layer, leading to wrinkles, swelling, or the formation of bubbles.
Causes and Correction >>
Poor Adhesion
A painted surface with an uneven texture, resembling the skin of an orange.
Causes and Correction >>
Cracking
Irregular cracks with varying depths appear on the paint surface. Cracking often occurs in repair areas or along the edges of the surface.
Causes and Correction >>
Wrinkling
During the drying process, the surface paint dries at different rates, causing unevenness in the paint surface.
Causes and Correction >>

Poor Drying
The paint film does not dry properly after the normal drying time and may require an extra-long drying period or not harden at all.
Causes and Correction >>
Clouding or Mottling
Uneven color or poor metallic effect is caused by sprayed paint being of varying thickness, and the silver particles are poorly distributed.
Causes and Correction >>
Sanding Marks
Sanding marks from the substrate or primer become visible after the paint surface has dried.
Causes and Correction >>
Putty Marks or edge Shrinking
Areas treated with polyester filler may experience issues such as filler marks or edge shrinkage.
Causes and Correction >>
Paint Mist, Dry Surface
During the spraying process, paint mist settles on the surface, making it rough and full of tiny particles.
Causes and Correction >>
Color Floating
The particle size, shape, and density of pigments cause the uneven distribution of pigments in the upper and lower layers.
Causes and Correction >>
Putty Patch or Substrate Scratches
During the paint drying process, the topcoat loses its gloss.
Causes and Correction >>
Polyester Putty Adhesion Loss
Loss of adhesion between polyester putty and the substrate.
Causes and Correction >>
Off Color, Color Mismatching
The color of the repainted area differs from the car's original color.
Causes and Correction >>
Transparency, Poor Coverage
The primer or previous coat is visible through the topcoat.
Causes and Correction >>
Fade of pigment
Color pigments change after prolonged exposure to sunlight.
Causes and Correction >>Guide to Identifying and Correcting Automotive Painting Problems
Why is this guide useful?
Automotive painting is precision work where even a small error can affect the quality of the final result. Paint surface defects such as loss of gloss, fisheye pits, color variations, or cracking can occur for various reasons, such as incorrect mixing ratios, improper spraying techniques, or environmental conditions. This guide will help you:
Quickly identify errors: Clear descriptions and visual examples will help you locate and understand the paint surface issue.
Understand the causes of errors: Each error is described with its likely causes, so you can prevent the same mistake from occurring in the future.
Receive clear correction instructions: Concrete corrective measures are provided for each error, helping you restore the paint surface to the best possible condition.
How to use the guide?
Browse through the different types of errors in the guide and compare them to the problem you encountered in your work. Each section contains clear images and detailed descriptions that help ensure you identify the correct error. After that, you can read the correction instructions, which are given step-by-step. This allows you to act quickly and effectively, saving time and improving the quality of your work.
With the help of this guide, you can enhance the quality of your automotive painting and reduce the additional work caused by errors. It is ideally suited for independent automotive painters as well as teams looking to develop their skills and ensure high-quality results for their customers.
