Reflection board for dent repair
Use reflected patterns to locate distortion without mistaking one view for proof of a finished panel.
A reference reflected by the panel
A dent-repair light or reflection board provides a controlled visual reference on the surface. Lines, bands or a fade pattern change appearance as the panel contour changes. This helps an operator see small deformations that ordinary room lighting may conceal.
A reflector board uses available or directed light; a powered repair light provides its own illumination. The useful choice depends on the work area, access and the pattern the operator can interpret reliably.
Read a contour, not just a stripe
Reflected patterns change with the board position, viewing angle and the original curvature of the panel. A straight-looking stripe is not a universal definition of a correct surface, because many vehicle panels are intentionally curved or creased.
Compare the damaged area with the surrounding original shape. Do not use a blanket rule such as wide lines always mean a low spot without considering the setup. Move the viewing position or reference to clarify an ambiguous shape.
Guide the tool and check the response
For pushing or glue pulling, the reflection helps locate the target and observe how the panel responds. It can reveal both the depression and raised surrounding areas. Tool or tab placement should follow that observation rather than a rough visual estimate made before the light is set.
Keep the reference stable enough to interpret a change, then reassess after a controlled correction. Lighting does not control the force for the operator; a clear view still requires a suitable tool, access and repair technique.
Use more than one inspection view
Reposition the light and viewing angle during final inspection so a remaining high or low is not hidden by a favorable reflection. Check the wider contour as well as the small area where a tool was applied.
A board is a visual aid, not a calibrated measurement of panel thickness, metal strength or paint integrity. It cannot establish structural safety or legal repair status. Where damage extends beyond cosmetic contour, the vehicle’s repair requirements remain the deciding reference.
