I just used a higher quality masking tape bought at the big green shed.....it was yellow in colour and supposed to be ok for remaining on a job for a long period of time. Left no residue on either of the EX builds which meant the tape was on for at least 4 - 5 months covering the edge and top of the rosewood fret board. Mind you I did cut out a bit of that plasticky stuff the necks were packed in to cover the Fret Board and then brought the tape across from the dot marker edge....you what I mean.
