I'd agree with @Sachakins - ex-biker used to clock up a lot of miles and always carried a gunge kit just to get you home. in 10y of riding only had to use it once - was in rush hour traffic one winters evening on the M40 just past the M25 junction and there'd been a rear-end in front of me, glass and debris everywhere and in the dark pretty difficult to avoid. Got home without drama but following morning had a flat rear so pumped it up with the gunge and rode into London carefully to head to my favourite tyre shop in Catford - Watlings.
They were not pleased when they took the old tyre off, loads of solvent used to wash the residue of the alloy rim and the tyre was replaced, the original having been punctured by what looked like a bayonet headlight holder, so multiple incisions in a ~10-13mm circle.
They charged me an extra £25 for the privilege but super service and no waiting for a recovery vehicle besides the motorway so all-in-all worth the extra!
