Tape off the logo so you don't mess it up. Then, sand the neck, but avoid the tape as much as possible. If you sand the tape, get a new piece. Then spray the primer. The logo should be covered up, but be sure there is no primer getting under the tape. You might want to get a new piece of tape now. Then, spray the color making sure nothing gets under the tape. Now, take the tape off and clear everything making it smooth and flush with the logo.
