That "human icicle" line hits home. I always figured sealant just had to cure on its own, no shortcuts. But hearing about the hairdryer trick made me try it, and now I'm not freezing my hands off every winter. It's one of those simple fixes you kick yourself for not thinking of sooner. Guess common sense isn't so common when you're half frozen.
You mentioned it feeling like a "shortcut," but idk if that's quite right. I mean, the heat from a hairdryer is just helping the chemical reaction happen faster. It's not really skipping a step, it's more like giving it the right conditions to work, especially in the cold. Maybe it's just me, but calling it a shortcut makes it sound like a cheat, when it's actually a pretty normal way to get the job done right.
