Place the replacement rocker panel into the hole in the rocker, and line it up on all sides. This may be difficult to do depending on the size of the rocker, so if you need to, clamp the sheet metal to the vehicle using the vice grips.
Open the door of the vehicle and place the replacement rocker panel over the rusted rocker panel. This should fit fairly tightly over the panel, but not perfectly since it is designed to replace the panel. Mark the edges of the replacement rocker panel onto the sheet metal below using the permanent marker.

Tack weld the perimeter of the replacement rocker panel to the vehicle using the MIG welder. A tack weld is a quick, short weld where you hold the trigger for no longer than one second at a time. By doing tack welds around the perimeter of the replacement rocker, you will minimize any warping that could happen from the heat of the welder. Make sure to move your tack welds around the panel frequently to minimize heat.
