It will polish up with fine grit seems to have a tin or ss look coating , but if you go too far you reveal the copper lining it has , before hitting the zinc alloy i tried polishing out a scratch hence i iknow has copper coating under it
,
But the mod once done is pretty sweet , good power through out , down to its 3.3v cut off , ive Ordered more supplies/ parts to do another will try do this one better
Since i got jist of how too now. First was a prototype to see if it was possible.
So im pretty impressed with how good it hits very little difference to a full mech.
Also ordered larger / taller mod maker bottles. Be arriving this week,
these new ones are supposedly 9.2ml so should hold 8ml or s with tube and only need refilling on each new cell. same width same cap just taller ,
