Has anyone used a tire leak sealing agent on a tube tire that is safe? I have a slow leak in the valve stem, and have replaced the inside of the valve, but still have a slow leak. Any other tips, before I have to replace her?

 

Scout,

The sealers that you are talking about (Fix A Flat) is a temporary fix only. It's made to get you home. You are filling your tire or tube with a foreign material that can effect the balance of your tire. It will eventually start leaking again. Time for a new tube[:@].
