Puncture rpair spray..

[dragonfire]

So i was reading a newspaper report about the potential outcome of usaing aerosol glue in spray cans to fill up and repair tire tubes the same time.

Cliffs: don´t use that - get liquid gel and a separate punp if you feel the need for that, the car makes have it separated in two modules out of good reasons.

Here comes the newspaper story in cliff form:

a man wanted to fix his inflatable swimming matress ( rubber material like bicycle tubes). Instead of simply patching it like on bikes he bough a spray can with glue in it that both inflates and fixes the tire at the same time.
it worked well, so the next day he decided to top off the filling with air and connected his electric pumk ( replaceable with weird electric interference or smoking a cigarette ) and a flame that burnt both his arms came of the vent. then the matress exploded hurting his and his daughters ears and moving a wall of his appartment by 3-4 inches outwards so the whole house had to be evacuated; the guy is not only facing medical treatment but also apunishment foruncautious handling of explosives and causing a detonation ( depending on judge´s opinion about the case potentially a bigger deal).

so don´t even buy these combined cans, otherwise you´ll have a permanently activated "bomb" in your tire.

Hmmm.... sounds like a case for snopes.com.

I just read the can of fix-a-flat I have, and it says "non-flammable". Tried spraying and lighting it, puts the lighter out instantly.

I have heard that the "puncture seal" brand uses something flammable, and that people have been hurt by it.

They used to use Propane as the propellant in the years following the banning of CFCs in aerosol cans. Fix-A-Flat type products used to come with a sticker you were to put on the valve to alert tire shops that the air in the tire might be explosive.

Most companies reinvented the product with in a few years to use a non combustable propellant and glue.

Never fill your tires off a tank of pure compressed oxygen either. Or do other dumb stuff, like clean parts with gasoline while smoking. Every few years some darwin award winner shows up on the news from doing that. Amazingly stupid.
