Ahh ok. These are aren't exactly rebuildable, they're meant for newer vapers and you just change the coil head out for a new one without worrying about rebuilding. Rewicking will still extend the coils life though and keep the vape fresher. You can still dry burn them but just have to be real careful, and only "burst fire" it meaning just hold it down til it starts to glow and let go, then repeat a couple times. If you try to hold it down too long the wire will "pop" it breaks like when a light bulb filament burns out. Sorry I'm just trying to figure shit out I'm probably just confusing the hell out of you haha
But he dry burns at about 6:40 in the video. Burning that crust to ash then rinsing ut off and rewicking will get the flavor back to nearly as good as new basically
