How long does Fix-a-Flat work? Do I need to get a patch/plug repair for my tire, or can I leave Fix-a-Flat in there permanently?
As stated on the can, it is important to have your tire inspected and repaired within 3 days or 100 miles (whichever comes first). Be sure to notify the qualified tire care professional that Fix-a-Flat has been installed. At the time the affected tire is inspected by a tire care professional, they should clean the sealant from the tire, prepare the area and repair with a U.S. Tire Manufacturers Association (USTMA) approved patch/plug.
