07cob, there is no problem fixing punctures once finilec has been used. The tyre repairer stands back from the wheel to let the gases out of the rim/tyre when he breaks the air seal. Once the tyre has been removed they wash the inside of the tyre with water to remove the residue from the Finilec.
As far as carrying extra tools I have a little ritual that I follow every time I take delivery of a new car. Ive only ever bought 1 secondhand vehicle when I was about 18 years old, a 4 cylinder ute that came without a jack or spare tyre, so I remove the jack and spare from every car Ive ever bought since then.
Knock on wood, so far so good!

Regards.
