Bolted body panels have become increasingly common over recent years, with many vehicles now using bolted front wings, front panel assemblies, bonnet slam panels and bumper bar supports. Obviously accident damage on such cars is much easier to repair, allowing simpler removal/refit of panels, and also easier preparation and painting in some cases. Panels can be prepared, primed and painted "off-the-car" if a good colour match is possible. A close visual inspection usually shows exactly where a particular panel is bolted. Some preliminary dismantling is usually required, as fastenings may be hidden behind wheel-arch liners , bumper bars.
