Abstract: In hot ambient conditions (particularly in climates having strong sunshine) vehicle glazing panels can reach high temperatures frequently in excess of 50° C. and on occasions up to 90° C. plus. In such high temperature conditions it is a known problem that small glazing panel breaks or cracks can become elongated (or result in shattering of the glazing panel) when stresses are applied to the glazing panel. The invention provides a method of repairing a flaw (such as a crack or break) in a vehicle glazing panel by first, wetting the surface of the glazing panel in the vicinity of the flaw and then generating a forced air flow to enhance evaporation of the wetted glazing panel, and subsequently conduction a repair process on the flaw.

Abstract: A method of investigating a glazing panel is disclosed in which a first investigation image of a target zone of the glazing panel is captured and a second investigation image of the target zone is captured. Image data from the first and second investigation images are combined to provide an output representative of the condition of the glazing panel at the target zone. The two investigation images are taken using respectively a black and a white background on the other side of the glazing panel.

Abstract: A canopy structure arrangement particularly for conducting repairs on a vehicle has a support frame re-configurable between a collapsed configuration and an expanded configuration; and an expansion support such as a tether to support the frame as it is manually expanded from the collapsed configuration to the expanded configuration. A ground anchor arrangement provides securing of the canopy structure. The arrangement permits ease of erection of the canopy structure.
