In the world of auto body repair, the term "blend panel" is commonly misunderstood and often misused. Many assume that blending paint into an adjacent panel is a quicker, simpler process than a full refinish, but in reality, the process involves more than just "fading" color into the panel. Properly blending a panel requires specific preparation, materials, and techniques that go beyond a simple touch-up.
In fact, the industry-standard practice of applying a "wet bed" of transparent base coat over the entire panel before spraying the new color means that the so-called blend panel is, in essence, a fully refinished panel. This process requires additional setup, labor, and materials, which justifies additional refinish time on the repair estimate.
Let's break down the proper refinishing process and explain why blending isn’t a shortcut, but rather a meticulous and time-intensive procedure.

The Myth of the "Blend Panel"
The term "blend panel" implies that blending is somehow different or less involved than a full panel refinish. In reality, the preparation, application, and curing processes for a blend panel often mirror those of a complete panel refinish. The difference lies in how the color is applied, but the time, materials, and effort required remain substantial.
Blending paint is a critical step in achieving a seamless color transition between repaired and adjacent panels. However, without the correct technique—specifically the application of a wet bed of transparent base coat—the results can be inconsistent, leading to mismatched color or premature paint failure.

The Proper Process for Refinishing a "Blend Panel"
1. Surface Preparation
The panel must be cleaned, sanded, and prepped like any other panel receiving paint.
Existing clear coat is carefully sanded to create a surface that promotes proper adhesion of the new paint.
2. Application of the Wet Bed
Before the new color is applied, a wet bed of transparent base coat is sprayed evenly across the entire panel.
This step ensures consistent adhesion and color consistency while preventing the "halo effect" that can occur when blending without a wet bed.
The wet bed effectively turns the "blend panel" into a full refinish panel, as the entire surface is being treated, not just a portion.
3. Application of the Blended Color
Once the wet bed has been properly applied, the new paint is carefully fanned out into the adjacent panel, creating a seamless transition from the repaired panel to the blend panel.
This color application requires a high level of skill to ensure the metallics, pearls, and pigments align perfectly with the adjacent panel.
4. Clear Coat Application
Finally, the entire panel is sprayed with clear coat to protect the new paint and blend the finish to match the surrounding panels.

Why the Blend Panel Is Actually a Full Refinish
The application of a wet bed over the entire blend panel fundamentally changes the process from a "partial" paint job to a complete panel refinish. The time, materials, and expertise required to achieve a flawless result are equal to—or sometimes greater than—a full panel repaint.
Key Points:
The entire surface of the panel is coated with transparent base (wet bed) before color application.
The clear coat is applied to the full panel, not just the blended area.
Additional setup and prep time are required to ensure proper adhesion and color matching.
Result:
The term "blend panel" is misleading because the process involves the same steps as refinishing a fully repaired panel. From surface preparation to final clear coat, the panel undergoes a complete refinish process.

Justifying Additional Refinish Time
Because the blend panel process requires an extra setup stage—specifically the mix and application of the wet bed—and full-panel refinishing steps, additional labor time must be allocated. This time includes:
Preparing materials for the wet bed application.
Mixing and applying the transparent base.
Ensuring proper spray technique to achieve a seamless transition.
Allowing adequate flash time before applying color.
Insurance adjusters and customers alike should understand that blending isn't a simple task but a precise, labor-intensive procedure that ensures a factory-quality finish. Skipping or rushing this process risks poor results, mismatched paint, and reduced longevity of the repair.

Conclusion: No Such Thing as a "Blend Panel"
The industry needs to move away from the misconception of the "blend panel" as a shortcut or lesser task than a full refinish. When performed correctly, blending requires a full panel refinish with an additional, specialized step in the form of a transparent wet bed base coat.
Auto body professionals must educate clients and insurers alike about the complexity of blending paint and the need for proper compensation for the labor, materials, and expertise involved. By recognizing the process for what it truly is—a complete panel refinish—the industry can maintain the high standards of quality, durability, and safety that customers deserve.
