Tire Sealant

[DA BIG ONE]

I have pondering using this product "Ride On" and I am hoping to get feed back from those of you who may have used this, or know of it.

I see it can be washed out w/hose and water in worse case situation.

I wonder about tire balance more, then how well product actually works.
