Regardless of how you go about it, there is going to be a break in the paint where two colors come together. Therefore, an ideal solution (plus it adds some pop) is to lay down some pinstriping along that line. Pinstriping can either be laid down before or after the final coats of clear. (Pinstriping under the clear looks cleaner, and is recommended if possible.) I had local Tulsa, Oklahoma, pinstriper, Ron Meyers lay down some lines before the final coats of clear.
