I ride tubulars and always carry a small 2oz bottle of Stan's in my jersey pocket. My last puncture was about 15,000 miles ago, I hardly ever get a flat with tubulars. It took me a couple of minutes to squirt half the bottle into the tire. It sealed so well I could go a week without having to top off the air pressure. Of course you can just put it in a new tire and always ride with sealant in it but I don't puncture often enough to want to do that.
