OMG! I was JUST about to post regarding this. I torched my Igo-L Drip tip. It went
through a couple stages. First, blue them purple then bronze... So I tried my hand at the cap. It looks amazing. It fades from bronze on top to a purple on the bottom. Nice and even.
So I tried the center part of my Kamry K100.. FAIL. It looks great. Swirled purples and blues, almost like an oil slick. HOWEVER, the heat expanded the metal and the top part where the 510 connector goes popped out. It's press fit in there, and it no longer fits. I am glad that the
mod was cheap.
I may try to solder it, or a thin application of JB Weld, but I am not sure it will work.
