When the glass of an automobile's side mirror becomes cracked or damaged, it may need to be replaced. Replacing the glass in a side mirror is not a difficult task. Replacement glass panes can be purchased from automobile supply stores. In as little as a half hour, you can replace your damaged glass.
Remove broken pieces of glass from the mirror you are replacing. Wear gloves and eye protection.
Clean the plastic mirror base with glass cleaner and allow it to dry.
Remove the plastic from the adhesive strips on the back of the new mirror.
Apply black rubber sealant along the perimeter of the mirror base. This will help to further secure your new mirror in place.
Place masking tape or duct tape around the mirror to hold it in place until the sealant dries.
