You've probably seen these bright yellow cans at your local car parts store and wondered if the product really works. The short answer is Yes it does. While I normally don't endorse any products on this site, I can speak from experience that Fix-A-Flat is the perfect short-term solution to a flat tire if you don't have any other options. One can will inflate and patch a normal sized tire (follow directions on can). Remember: It is designed to provide a temporary fix so that you can make it to a gas station and have the tire professionally repaired.
TIP: Always carry a can of Fix-A-Flat in your trunk.
