This stuff does work as advertised but you DO NOT want to leave it inside your aluminum wheel for any extended period. I've changed about 150 tires over a two year period. I've had a few tires show up with this stuff inside. Every wheel that I've changed that had this stuff inside had heavy pitting in the aluminum from leaving this stuff inside the wheel as a permanent fix to a leaky tire. It's not meant to be left in. It gets you back on the road till you can have your tire fixed or replaced.
