I carry one of the el cheapo tire plug kits from Wal-Mart in my car at all times, although Ive only had to use it a couple of times, its saved several peoples butts, I work at a convenience store, so anytime someone walks up with a can of fix-o-flat, instead of thinking about the money were making, I make them another offer, but sadly I have to buy a refill for it about every week or so, because lots of people get flats...but id rather use one of those any day over the fix o flat stuff.....and its the same thing the tire shops use, theres are probably a little bitter...because theyre red right?
