Spent 15 years thinking I didn't need a stud welder for dents

I always figured a slide hammer and some patience was good enough for pulling dents on door panels and quarter panels. Then last month I picked up a cheap used stud welder from a guy retiring near Nashville and tried it on a tricky crease on a 2014 Civic. Has anyone else had a tool they swore was unnecessary that turned out to save them hours of work?

Honestly, I'm still not convinced. A stud welder feels like a crutch when a slide hammer and patience will teach you way more about how metal actually moves.

Ngl, you're forgetting the biggest reason most shops switch to stud welders - it's not about skill at all, it's about heat management on modern cars. These newer panels are so thin and have so many layers of different metals that a slide hammer can actually warp the heck out of them if you're not careful. A stud welder lets you dial in the exact amount of pull without transferring all that hammer shock through the panel. Worked on a BMW last week with crazy thin quarter panels and the stud welder was the only thing that kept the metal from rippling like a potato chip.

Man I read a thread on another forum where a body shop guy said the same thing about heat management, and that's what finally got me curious enough to try one. Called a buddy who does classic car restorations and he told me modern panels are basically tin foil compared to what we had in the 90s. The stud welder just puts the heat right where you need it instead of banging the whole panel around.
