Wait now, It's just Ride on or Slime on steroids, It's like a spray in glue sealer type stuff, tire is not solid. This stuff is always tacky, moves only to seal a hole.
The price is not bad considering. If your doing an Iron Butt or part of some touring group out on a long range mission it's your duty to be prepared like that against tire failures so the trip goes well and your not the one holding up the ride. That's almost priceless.
Really? That's all
it is? Well, my mistake & I sit corrected.
From the illustrations on their website, I got the feeling they were filling tires with some revolutionary space-age material originally designed by NASA or something. They're just selling tires and some goop to go in them.
I guess I did pretty good paying $20 for my two bottles of Ride On, then...sounds like pretty much the same thing.
