1. Alclad I use it Love the results, much more durable then testors metalizers. But then, I don't handle my builds very often after completion.
2. I use a #11 blade, slip of the hand happens & easily fixed no sweat...
3. I use the Tamiya masking tape and a avid user of it alone. BMF for mask, haven't yet but maybe if in a pinch I would.
