Hot take: I used to swear by heat guns for stubborn solder joints, but a bad experience changed my mind

Thing is, heat guns dump heat everywhere and you end up cooking the board. I had a vintage synth power supply once where I was sure a joint was toast on a big capacitor. Hit it with the heat gun for maybe thirty seconds too long and warped the whole capacitor can, which cracked the base seal and ruined it. Switched to a controlled soldering station with a big tip after that and never looked back. You get way more control and you aren't fighting to keep the heat where it belongs.

@sarah_connor actually made me think of something, and it ties right into what @singh.blair is saying. You're both right about heat guns being messy, but there's another side to this. Sometimes the issue isn't the tool, it's that people don't think about the actual load they're working on. That vintage synth power supply, those old caps, they're way more fragile than modern ones. I've seen friends ruin gear by hitting it with too much heat because they didn't account for the age of the parts. Newer capacitors can take a beating, but old stuff, the plastic and seals get brittle over time. So you need to match your heat strategy to the gear's age, not just your own skill level. It's a detail that makes a huge difference and nobody brings it up enough.
