Need Stripe Help Please!

That's such a bad idea. That stripe runs through 3 panels. If you ever need to adjust a door (hinge replacement for example), or if the fender ever gets moved, you will be screwed.

You better have everything perfectly aligned and together when it's painted.

Agree... seen it before fender gets damaged stripe need repaint try to rematch that. Easy to swap out a decal stripe on the whole side.
But they do look pretty painted under that clear coat. My2c
