There are a zillion vinyl tapes made by 3M. Can you please give us a specific name, part number, etc.?

The packaging says 3M Vinyl Tape 471. The product number is PN 92385. Mine is blue...I don't know if they have other colors or if it even matters. I have a roll of the .125 in (3.17mm) width.
Here's an example: http://www.melomotive.com/~21239
It great for masking around curves, too. You can cut it into norrow strips and mask complex curves like aircraft canopies.
Tamiya sells their own vinyl tape, too. Of course, it is more expensive.
