I wrapped my copper clone with 1" heatshrink when I first got it, and it came out pretty nice too... feels really good in hand, no matter how much juice residue it has on it. 
I've been using an Infinite SS for about a week now (the only clone that's confirmed one-piece as far as I know), and it's time to wrap it with heatshrink too.
