Repair minor scratches in the RV aluminum siding by gently sanding the surface surrounding the scratch. Brush or wipe away the grit. Paint over the area with matching paint and allow it to dry. Another option is to spray paint over the scratched area to repair it.
Drill a small hole in the middle of a dent. Insert the self-tapping screw with a washer around it. Use the screw and washer as a pull knob to pop the dent out of the metal siding. Remove the screw and fill the hole with plastic filler putty suitable for use with aluminum. Allow the putty to dry and then sand off the rough edges. Paint the surface to finish the repair.
Remove badly damaged siding from the RV to replace it. Take off the side moldings from the RV. If the panel is a top one, remove the top molding as well. Remove the lenses for the clearance lights and other fixtures if the piece you’re replacing has them. Disconnect the lights from the panel. Either twist them out of the aluminum panel or unscrew them. Set all lights, fixtures and screws in a safe place.
Pull out the staples holding the aluminum panels in place with a pry bar. Avoid damaging the surrounding panels that you aren’t replacing. Pop the damaged siding out of its position.
Set the old metal sheet on top of the new one. Mark where the holes need to be for clearance lights and other fixtures. Also indicate any edges that you may need to trim. Use tin snips to cut the metal edges. A hole saw is useful for cutting out holes for the clearance lights.
Align the metal on the wall of the camper. Run the wiring for the clearance lights back through the holes. Attach the aluminum panel in place with staples. Put the lights back in place. Reattach the molding.
