A stubborn crease on a Civic quarter panel taught me a heat gun trick
I was working on a 2018 Civic with a dent right on the body line, and my usual hammer and dolly work wasn't getting it. Out of frustration, I applied my heat gun on low to the backside for about 15 seconds, then immediately worked the metal, and it moved way easier without oil canning. Anyone have a different method for sharp body line repairs?

@claire_walker your buddy with the torch story is exactly why I stick to the heat gun for delicate work. One thing though, you said he was trying to shrink a quarter panel. Actually heat shrinking is for stretched metal, like after a dent has been bumped out too far. On a sharp body line like a Civic's, you're usually just trying to soften the metal enough to work it back into shape without causing more damage. A torch puts way too much heat in one spot too fast, but a heat gun on low, like you said, gives you way more control. The trick is to keep it moving and never let it get hot enough to change the paint color, just warm enough to make the metal feel soft under your tool. That 15 second warm up from the back is usually plenty for a clean result.

Ever see a guy try to shrink a quarter panel with a torch? My buddy did that on an old truck, and he got it way too hot. The paint blistered right off in a perfect circle, and the metal went all wavy. He had to replace the whole panel after that mess. Your heat gun trick sounds way safer for controlling the heat. I guess the trick is just enough to help the metal move, not cook it.

My uncle used a heat gun on a dented fender, kept it moving in slow circles about six inches away. The metal relaxed back into shape without any color change. It's all about patience and watching the metal, not the clock.
