Vittoria's Pit Stop Corsa is the solution for punctured tubular.

Vittoria's Pit Stop aerosol fix-a-flat is claimed to be the only solution of its kind for a high-pressure tubular. Adding only 18 grams of expandable latex to the tire, the Pit Stop instantly inflates a narrow tire to 90 psi while filling leaks (other than cuts). You can continue to ride the tire, so this is not just a temporary fix; in fact, CSC's mechanics filled all of the team's tires with Pit Stops prior to Paris-Roubaix last year (and won the race). One note, though: the gas in the cylinder is propane, and being highly volatile, will all bleed out overnight, so you'll need to pump the tire up with air the next day. With a Pit Stop, a rider need not peel off or throw out a flat tubular; he or she can be back on the road immediately and can still wear the tire out before replacing it. And a Triathlete in a race using either tubular or clinchers need not carry a spare or spend the time to change a flat tire.
