I use to have a blue/white scrambler and did what you're thinking. A 1/4 blue stripe on the beveled/raised part of the front fender and a 1/8 or 1/16 gold stripe on both sides. There should be a pic of it somewhere on the site. Heres a double pinstripe i put on my bonne.
Just wipe it down w/ an alcohol pad and tuck a small amt of the pinstripe under the fender for a clean look.
