Fix-a-Flat for sidewall leak?

You forget.

It’s a TEMPORARY repair.


No I didn’t forget, but it appeared to me that the narrator of that video did gloss over that fact.

Watch it again.

He states it’s a TEMPORARY repair.


At 2:00 to 2:06, he says that you don’t have to clean it out and if it is left in there, it won’t hurt anything. This is the point of my disagreement. If left in there, the moisture will do serious damage to the rim. I have seen this numerous times, including one time to myself. The rust will ruin a rim is pretty short order, it caused a rim to crack on one vehicle after less than two years. I don’t know for sure but I suspect that it might also contribute to rubber rot as well.

BTW, I don’t say never to use it. There are times when it can be very useful, like if you are on a road trip, the car is packed like a woman’s suitcase and the spare is all the way at the bottom, and the weather is bad, like raining.
