I've seen Holts work from a new, freshly bought can. I've also seen the results from leaving a can in a metal pannier on a hot day. Take boots you can walk in? RAC card?
As for tubes been obsolete technology, I don't see why. I can change a tube in a tyre I fitted myself in minutes and it stays repaired indefinately. They are like anything else, let a quick-thick-fitup merchant near your bike and you can be stuffed by unloobed rims, tubeless tyres with tubes inside, gloop that stops the plugs working and so on. Know your bike and carry the kit is the only answer IMHO.
