PSA: I had to pick between a heat gun and a torch for a stubborn quarter panel dent

It was a 2008 Civic with a deep crease right by the wheel arch. I started with the heat gun, but after 15 minutes the metal just wasn't moving enough. I switched to a small propane torch, moving it in quick circles about 6 inches away, and the metal relaxed so I could work it out with my hammer and dolly. The key was keeping the torch moving to avoid any color change in the paint. Has anyone else found a better way to handle those tough, springy dents without risking the finish?

My old body shop teacher always said to never put a torch near factory paint if you can help it. That heat shock can cause the clear coat to fail months later, even if you don't see a color change right away. For a crease like that on a Civic, I've had better luck using a dry ice method to shrink the metal back cold, or just drilling a small hole for a slide hammer if it's really locked in. The torch trick works in the moment, but it's a big gamble on the long term finish.

Explain the dry ice method in more detail. I've heard of it but never seen it done right on a panel with factory paint still on. Does it risk cracking the clear coat from getting too cold instead of too hot?

Honestly, I gotta jump in here. @dakotab13, you're asking the right question about the dry ice method. Yeah, it can crack the clear coat if you go too fast or use too much, but the real risk is way lower than heat. Heat messes with the metal's structure long term, cold just makes it shrink back. I've seen torch jobs where the paint looked fine for six months, then suddenly the clear coat lifted like a bad sunburn. The dry ice trick works if you work slow and let the panel warm up naturally after. Slide hammer is still the safest bet for a deep crease though, no heat or cold needed.
