Good Trip Saver, The instructions say it works "continuously for 2 yrs" found out the hard way 5 yrs was pushing it, turns into a non working liquid that doesn't plug a hole. Between yrs 1-4 worked GREAT and saved many outings. You might get a light spray of Green liquid as it plugs a hole. Been using for over 10 years.
First off the product says it will last 2 years in the inner tube. I would assume then you need to toss the tube and replace it.
I had a leaky tube that I just could not find the leak. I added Slime to the inner tube and it has held air ever since.
