Ok here we go.
The foam in a can does work but to a max of 1cm hole.
If you get slashed tires (i've never had in over 10yrs of driving) your gone and you gotta ring a friend to bring the tire over. (that's the use of a gf!)
I don't drive much further than 30km from home and so i have the can.
It is like a strong glue that fills up your car so you can drive home.
I've put in a tire plug once i got home but it was better than i expected.
It also pumps up the tyre. 1 can can pump 1 tire about 3/4 full, which is enough to drive home.
P.S just be careful as this stuff is super sticky but clear.
