I got a gun metal in the mail today. Put a couple of SS 430 6 wrap 3.5 ID claptons in it, wick it up, and geez, where has this been? Wicking couldn't be easier, even for someone who can make anything leak. Smooth airflow, great machining. On my limited use so far, I'll have to have another. Like it was made to go atop the G Class carbon fiber. Subtank Supply had it to me in 2 days, they're great.
