Fix-a-Flat Update: Still Dangerous?

By October 30, 2010

Follow me on:

There is always lots of controversy surrounding Fix-a-Flat and other emergency tire repair products. The stuff is despised by most technicians at tire shops, thanks to its all-enveloping gooey nature and foul gases. But there have also been claims over the years that a can of tire sealant can spontaneously explode in the trunk of your car. Fix-a-Flat claims that this is absolutely not a problem. To be honest, I went along with their claim since it seemed to be based on science (and research, I hope), and I've personally never seen a can of sealant fail in that way. Then I hear from Brad, who claims he personally saw not one, but two cans of Fix-a-Flat explode in his trailer. I have no way of verifying his claim, so the best I can do is pass it on to you for you to digest.

I'd love to hear more thoughts on the subject, or more experiences if there are any.

Ive never seen one fail like that either. I’ve just always hated having to clean that stuff out of a tire in order to repair it. I see a lot of shops now though that flat out refuse to repair a tire if it has any kind of fix-a-flat stuff in it.

Fix a flat is a pure rip off! I am a ASE CERTIFIED TECH and had a flat on my car, and used a large can of fix a flat I carried in my trunk just in case I had a flat, I used the can of fix a flat as the directions spelled out. It hardly inflated the tire and when I did add air, it would not seal the hole caused by a roofing nail. Well I had to remove the tire and put on the spare tire that I should have done in the first place and I would be about $8.00 dollar richer. Live and learn at the best SCHOOL OF HARD KNOCKS!

It does not seal large punctures. I used it once to fix small pores caused in my aluminum-magnesium wheels by galvanic corrosion.
