Handling & Mounting Hoods / Bonnets During Collision Repair
Table of Contents
Introduction
Hood or bonnet panels are large exterior panels that cover the engine compartment and are typically constructed with a thin outer skin supported by an internal reinforcement structure. Once removed from the vehicle during collision repair, the hood becomes a large and awkward panel to handle because of its size and relatively low rigidity.
The wide surface area makes the panel difficult to support evenly when it is off the car. Without proper mounting the hood can flex under its own weight or shift while technicians are working on it. Stable support is therefore essential to prevent distortion, protect the panel surface and allow technicians to carry out repair and preparation work safely.
Handling Challenges
The wide, flat design of a hood panel means it can flex easily if it is supported unevenly once removed from the vehicle. Although the panel may appear rigid while installed on the car, the surrounding body structure normally provides much of the support.
When the hood is off the vehicle, that structural support disappears. If the panel is supported only at the edges or placed on an uneven surface, the center section can flex or sag. Aluminum hoods are particularly sensitive to this because the material can distort more easily under pressure.
The size of the panel also creates handling challenges in busy body shops. Hoods take up significant space and can be difficult to maneuver through work areas without stable mounting.
Common Mounting Mistakes
One common mistake is placing the hood flat on a workbench or against the floor. This can scratch the painted surface or place pressure on unsupported areas of the panel.
Another mistake is supporting the hood at only two points, such as the corners of the panel. Because of the hood’s width, this can allow the center section to flex slightly while technicians work on it.
Leaning the panel against walls or other vehicles is also common in busy shops, but this often leads to bent edges or accidental surface damage when the panel shifts or is knocked during normal workshop activity.
Correct Mounting Approach
The hood should be mounted vertically or at an angle on a hood stand or panel stand. Ideally it should be supported through hinge mounting points or along the internal reinforcement structure.
Body Shop Workflow Considerations
Hoods are often removed early in front-end repairs and pass through inspection, repair, preparation, and refinishing stages. Keeping them mounted on mobile stands reduces unnecessary handling.
Equipment Used
Because hood panels are wide and relatively thin, equipment that spreads the weight of the panel across multiple support points is essential. Adjustable panel stands allow technicians to position the hood securely while maintaining full access to the working surface.
Mobile stands are particularly useful because the hood can remain mounted while being moved between repair areas, preparation bays and the paint booth. Keeping the panel on the same stand throughout these stages reduces unnecessary handling and lowers the risk of damage.
