Puncture safe every time. Small holes sealed before you know they exist. Large hole deflate less rapidly giving more chance of stopping before tyre has you off.
Definite vote for the Stop n go kit. But you have to remember there is no such thing as a guaranteed result with any repair kit dependant on what has caused the puncture. Do not use any form of slime (filler) if you have tyre pressure sensors.
My tyre pressures sensors are fine but I avoid cheap goo and blow through open valve before fitting the cores.
Had alloy corrosion with some goo but no problem with Puncturesafe.
