Right, got rid of the Renaultsport badge today, thought it looked tacky, didn't take any effort at all tbh, and mines a 56reg, the outlines were quite heavy on mine, a bit like the one on the picture in this thread.
First of all I used tar remover, left it to soak for couple minutes, buffed off with a microfibre, which removed a lot of the residue and marks on the paint.
Secondly I clayed the area which didn't really get rid of much more of the marking but it did help prep the paintwork that hasn't really been touched before.
Thirdly I used a bit of good old super resin polish on the whole area, which got rid of any left over marking without any effort whatsoever, just used circular motions in the area for 30seconds or so, then let it cure on paint for a little while, buffed off with microfibre.
Lastly I waxed it with collinite 845, to lay a bit of protection.
Nice and easy took me all of 15mins to do if that.
