I use the Orange Seal for punctures in my tubular tires. Several punctures fixed due to the broken wires of worn vehicle radial tires. Orange Seal takes care of these punctures with ease. Orange Seal is my go to sealant for tubulars.
My first tubeless setup in my road 700 x 32 tires and about 800 miles, picked up a piece of glass and sprung a leak on a front tire, yes I did get sprayed with sealant but in about 1/4 of a mile the tire sealed itself and I was able to remove the glass piece and added more sealant to the tire and have ridden that tire another 1300 miles with no problems. I added 2 oz on the initial setup and add 1 oz about every 45 days or so to keep liquid in the tires due to the South Florida Heat.
