I agree in principle with Boaterva.
If you have a small leak a 12V tyre pump will save the day. Even if the nail is still in the tyre.
If you have a big damage there is only a new tyre that will help you. Get road side help.
The goo is for the rare situations where you get a medium leak far away out in nowhere and you have no other way.

I have used goo once, while driving off road with another car.

But a 12V tyre pump is a sound investment.
