1 the powder was really erratic, sometimes none or hardly any would come out, other times when you pulled the trigger it would pour out the end, what am i doing wrong?
Try shaking the cup really good to "fluff" the powder, or get the clumps out.

2 if i have polished aluminum or SS do i have to do anything to it besides cleaning it to get it to adhere properly? if you scuff it and clear it do you lose the polish effect?
Cast Aluminum needs to be outgassed, or heated to just above cure temp first. Extruded aluminum I shoot just like any other metal & never had a problem, though more experienced coaters may differ. If you're shooting translucent or transparent colors or clear, yes you will lose the polish effect if you scuff it. I give a light scuff for solid colors.
3 it didnt seem to me that the powder was flowing to the part too well, is it supposed to be noticeable or do you normally lose twice as much powder as gets on the piece?
Check your ground.
thanks in advance, will be doing more tomorrow.

Hope this helps, good luck! & welcome to the forum!
