I think it's fine for a temp fix or road side repair. I carry a couple of cans with me on my adventures, just in case...
I've heard good things about the 'tape' they have too.. I've not personally used it, but again, a quick fix just like a spare tire..
I have used the spray on other things and seems to work and sealed what it needed to seal until I could fix it. Outdoor shed roof leak..
Good luck.. Mitch
