1. Understanding Paint Dripping and Runs

Paint drips and runs are common imperfections that can occur during the automotive painting process. These blemishes arise when wet paint accumulates excessively on a surface, gravity then causes it to flow downward, resulting in an uneven and unsightly finish. Understanding the causes and characteristics of paint drips is essential for effective repair and prevention & auto body repair.

1.1. Causes of Paint Dripping

Several factors contribute to the formation of paint drips and runs on vehicles:

Over-application of paint: Applying too much paint in a single coat increases the likelihood of drips.
Incorrect spray gun technique: Holding the spray gun too close to the surface or moving it too slowly can lead to excessive paint build-up.
Improper paint viscosity: Paint that is too thin or not properly mixed may run more easily.
Environmental factors: High humidity or extreme temperatures can affect paint drying time and increase the risk of drips.
Uneven surface: Painting on uneven surfaces can cause the paint to pool and drip in certain areas.

1.2. Identifying Different Types of Paint Runs

Recognizing the type of paint run is important for choosing the right repair method. Common types include:

Sagging: Occurs when a large area of paint sags downward, creating a wavy appearance.
Curtaining: Similar to sagging but with a more pronounced “curtain-like” effect.
Stringing: Thin, vertical lines of paint that drip down from edges or corners.
Pooling: Accumulation of paint in low-lying areas, forming puddles that can lead to drips.

3.3. Applying Automotive Paint

Clean the Surface Again: After sanding, clean the area with a tack cloth to remove any dust or debris. Ensure the surface is completely clean and dry before proceeding.
Prime the Area: If the sanding has exposed the primer or bare metal, apply a thin coat of automotive primer. This will help the paint adhere properly and provide a uniform base.
Mix the Paint: Follow the manufacturer’s instructions to mix the automotive paint with the appropriate hardener and reducer. Use mixing cups and stir sticks to ensure accurate measurements.
Apply the Paint: Load the paint into a spray gun and adjust the settings for optimal atomization. Hold the gun 6-8 inches from the surface and apply thin, even coats of paint, overlapping each stroke by about 50%. Allow each coat to dry before applying the next.

3.4. Applying Clear Coat

Apply Clear Coat: After the final coat of paint has dried, apply several coats of automotive clear coat. This will protect the paint and enhance its gloss and durability. Follow the same spraying technique as with the paint, applying thin, even coats and allowing each to dry before the next.
Wet Sand the Clear Coat: Once the clear coat has fully cured, wet sand the area with 1500-grit or 2000-grit sandpaper to remove any orange peel or imperfections.
Compounding: Apply a small amount of rubbing compound to a buffing pad and use a polishing machine to buff the area. Work in small sections, using a circular motion and moderate pressure.
Polishing: After compounding, switch to a polishing compound and a clean buffing pad. Polish the area to restore the gloss and clarity of the paint.
Waxing: Apply a coat of wax to protect the paint and enhance its shine. Use a soft cloth to apply the wax in a thin, even layer, and then buff it off to reveal a glossy finish.
