Anyone ever had to use tyre foam that's out of date? Realise tyre foam is far from ideal anyway, but for the first time since owning the car I decided to see what was in the box. Lovely can of tyre foam with a Ferrari sticker and the words "Expires end Nov 99"! The amusing part about this is that the car was first registered Jan 99!! Am pretty sure I'll just not bother putting the package back in the car (extra unnecessary weight ), but was wondering if anyone had used an out of date can of this stuff?
