almost anything will work to "get you home" but many tire service guys will not work on a tire with fix a flat or slime in them. It makes a mess of their machine and can be dangerous too.
Only the fact it wont work on tubes...it will simply leak inside and get around the tire and make a mess, your tube will still leak..
Ok, he said a tubed tire.
A plug won't work.
Fix a flat or Slime WILL work on a tubed tire. I've used both. Why wouldn't a tech work on a tubed tire, that has had FAF used? It's contained by the tube. Throw it away. By the way, Fix-a-flat hasn't used a flammable propellant in more than 10 years.
Some bad info out there... Don't perpetuate the myths.
