You have to have slime in the tire in any case if your run tubliss.
Remember.
Tubliss alows you to run real low pressures. More traction, and no pinch flats (Where your wheel hit a rock, and pinches the tube between teh inside of the tire and the rim thereby cutting it)
Then, for thorns and small holes, the slime seals it no problem.
Sometimes though, you get a cut or a branch making a bigger hole. nothing seals that. That is where you pull out the puncture repair kit and fix it.
I carry co2 canisters with me for when that happens and im up and running again.
Then you do patch, you use those metal spokes at an angle. You will not damage your inner of your tubliss.
Also remember.
I have finished the last lap on my bike with a completely deflated front tire and i did not even notice. The tubliss system allows you to run your tires completely deflated relatively safely. The tires do not come off the rims.
