3m Scotch 218 Fine Line Tape?

[twilight]

Does anyone use this product for masking off pieces before painting/airbrushing? I came across an article about it on another website, last night. Comes in various sizes from 1/16 to 1/4" I found so far. If anyone does use it, what is the most convenient size? I have a couple of Reading GP30's I want to get in the paint booth soon and looks like some delicate masking off in the cab area has to be done.

Thx,
Mark
