Tufo Tire Sealant - 50ml $12.00
Puncture insurance from Tufo for your road tubeless tires.
If you love to ride tubulars, Tufo Tire Sealant is as close as it gets to an insurance policy. You can use it preventively by unthreading your tire valve and squeezing sealant directly into the tire. If/when you get a flat the sealant plugs the flat, often times with almost no pressure loss. Alternatively, you can use it after a flat, since the sealant can plug holes up to 2mm in diameter. One 50ml bottle is good for 2-3 tires. And note that this sealant comes with the bonus of one Tufo valve removal tool.

This is junk
This is junk. Open bottle, insert into tire, ride Tufo tire, get flat, pump, listen to air escape, repeat.
Save your money.
This stuff does work! I bought a bottle of this for "emergency" purposes, and tested it out to see if it really worked. It does. Goes in through the valve stem in a pinch, and sets quickly. It will quickly fix a tire, and get you going. It however leaves your tires out-of-plum, and generally calls for them to be replaced anyways. This just prevents you from getting caught out in the middle of nowhere. Worth keeping in that emergency bag.
