Must have for road trips
Size: 16oz (Pack of 2)
Works awesome. If you don’t use them within a year replace them. It’s way cheaper than a tow truck!

Bad Product
Size: 20oz
There was no pressure in the can. It would not even inflate a bicycle tire. Be careful there is no amazon refund or return with this item!

IT WORKS, IT REALLY WORKS!
Size: 16oz, Size: 16oz
I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!
