Be careful using in convertibles it will blaze a hole in the roof.
I have also used it to braze a tie rod end enough to get my jeep out of the bush after I snapped it hitting a stump.
In a pinch I have used it for added acceleration in the car.
I found it to be a sufficient accelerate to start small thermonuclear reactions in my garage.
I saved the life of myself and 8 other tourists when the flame unit on our hot air balloon died, the vector was sufficient to allow us to land in a normal fashion.
