Anyone got a good online source of really narrow tape that I can use as a masking tape to create indented panel lines (i.e put the tape down, shoot primer, sand lightly, pull the tape off to leave an indented line that will still show slightly when the color is shot over it). I used to use some really fine Kyosho tape, but am having a hard time finding a source just now.

The tape needs to be considerably thinner (widht wise) than the 1/6" tape that is the smallest I've found online so far.

Thanks in advance for any help you can provide,

Gordon
