If you use rubbing compound be very careful.It can completely remove paint.when you are done clear coat it so it won´t fade as quickly.(it might be easier to remove it then try and mask around it)As far as the stripes mask the line and despite the curves of the body make sure the painted edge stays straight and doesn´t get distorted as it conforms to the curves.Make sure you are absolutely certain before you paint.My car´s paint needs help but before I get it done I am playing with some idea´s and applying them so I know what it will look like before I spend the money to have a custom paint job done.So far I haven´t screwed up(knock on wood)The only part that sucks is I´ll loose the graphics when they repaint it so I´m not in too big of a hurry.
