Stripe question with 2 roll bars and scoop...final prep for primer

[Valkster]

Hi, again. A quick question about using the string line I pull after spraying the stripe base color on the body to mask everything off. Is it typical to pull a 1" temporary tape line using the string as a reference down the body, or do I use the string to measure for small pieces of tape offset on both side of the string to pull my fine-line tape? Most photos I have seen show the string pulled down the center, then later the fine line 1/4" (I think) to make the inside border for the wide stripes but nothing in between.

Thanks yet again,
Mark
