Vehicle designation removed, leftover edge!

Hello together, maybe you can help me! The following: Today I removed the TT logo at the rear of my 8N from 2002 via household floss, floss, fingers and various harmless mediums. Unfortunately I had to find out, despite repeated polish a small outline remained in the paint! I ask myself until now whether this outline actually “sits” in clear lacquer or if it is still to be removed. I tried to take a photo, which was unfortunately not quite so easy. mriss is really hard to recognize, from “somewhat bigger” distance (from about 1m) you can only see it from certain points of view. Maybe someone has an idea how I can still remove the outline without repainting half the rear! Polishing was the PF2500 of Menzerna and a cheap “grind paste” of Sonax and my LE T3000 machine…. Glad to hear from you! Greeting Stefan
