I've had a puncture a grand total of once, and to remedy it I used a repair kit. It worked without any issues. I even had a mechanic inspect the tyre after and he said it was completely fine to drive on it after because of how well sealed the puncture got, which is to be fair not the recommendation from the kit manufacturers, but as I understand, the tyre held up fine for a long time after that. This was not my car, I don't own one and I drive quite rarely
