The stories of bodily injury and death by explosion pop up almost instantly when you mention Fix-a-Flat in the company of a seasoned auto mechanic or tire tech. I say seasoned because it's usually older guys that tell the stories. I'm here to tell you with 100% conviction that Fix-a-Flat will NOT explode! If you're using another product, be sure to check it out, but the Fix-a-Flat brand is non-explosive and can be used without risk of injury to the person who is removing the tire. Messy? Oh yeah. But not deadly. I could go on and on about this, and since I can write whatever I want, I did go on and on about it here! Read up on the history of the explosion myth and why there's nothing to worry about.
