I have three sets of tubular wheels needing new tires each year. The tape has made this spring ritual so much more easier. This is my first time removing the tape, so I can't comment on the tape removal as of yet.
I bought some Tufo tubular clinchers last summer, and while the weather was nice, didn't need to use this. Once the fall got rolling and the weather changed, I had a bunch of punctures, not all of which were sealed by this stuff. And a few that were sealed later blew out while riding. I know, I know, I should have changed tires before the weather got bad, but the tires are soooooo comfortable to ride on! I'd say use it, but don't totally count on it saving you. I have my winter tires on now. I'm not sure I'll go back to the Tufo setup in the summer.
This stuff is amazing. It's pretty rare that I get a puncture that can't be fixed with this sealant. And in most of those cases, the tire will still hold enough air to get me home.
Once the bottle is opened, the sealant tends to set pretty fast, so if you use half a bottle to fix a flat, the remaining sealant won't last more than another month or two without becoming hopelessly gummed up.
I usually bring a small finishing nail in my bag to push through the nozzle to make sure it allows the liquid to flow.
I've been riding tufo tubulars almost exclusively on my road bikes for the past seven years. My friends often ask my why I'm not concerned about flats and the hassle of changing tires. This product is a big part of the answer.
I don't get that many flats with tubulars in the first place (particularly the Tufo Elite Ride), but on those rare occasions when I do, a third of a bottle of this stuff squirted into the tire by removing the valve core fixes between 80 and 90 percent of the flats. And most of the time when it doesn't full seal up the leak, it will at least keep enough pressure in the tire for me to finish my ride and change the tire in the comfort of my home or hotel.
