Showerthought: The heat from a torch can warp a quarter panel from three feet away.
Read it in an old trade magazine at the shop. They said the metal can start to move at 400 degrees, even if you're not aiming right at it. Anyone else run into this on a big repair?

Yeah, that line about the metal moving at 400 degrees... it's real. I read something similar about how heat spreads through sheet metal. You can be working on one spot and the heat just travels, makes a whole different area go soft and buckle. It's why you see guys using heat shields or wet rags now, to try and trap that spread. Makes a tough repair even trickier.

Honestly patriciah99, that's why I always keep a spray bottle of water on hand for any panel work. A quick mist on the area around your weld can really slow down that heat creep. It's a simple trick but it saves a lot of headaches.

That part about heat just traveling through the sheet metal is so true. It's like patriciah99 said, you fix one spot and mess up another. I see this kind of thing happen all the time, not just with cars.
