The rivet gun needs to come from your own tool box (or you can order one from Eastwood). As each rivet is installed, it pulls through the glue, which in turn enables the new panel to be pulled flush against the stock panel. The rivets essentially become welded in place. Not shown here is the lower section of the panel, which is held in place with about a dozen Vise-Grips and sheetmetal screws. Once the glue sets up (about 24 hours), the Vise-Grips and screws can be removed.
