I find the tamiya tape excellent, burnished down with a cocktail stick, and then some maskol or equivalent to ensure gaps where tape meets are fully sealed.
The other tip with masking, (if I am not teaching my grandmother to suck eggs!) is when spraying spray at 90 degress to the tape or over the tape on to the models, not towards the tape, if that makes sense) to avoid any creep under or build up along the tape.
Look forward to seeing it a new colour, the red is not to my taste either.
