Hood Springs: Heating with a torch to reduce tension (while on the car???)

We'll, I can see one way this could end well. However, I see 43,674 ways that it won't.

Which is exactly why I'm asking for the sage wisdom of the forum. :D

It may not be crazy though. It is pretty easy to isolate the areas being heated with the torch, don't you think? How many of us have resorted to the ol' flame wrench when battling with a stubborn nut...and somehow not burned the car to the ground. :D
