hmm , id have liked to have seen a pic before you put any lacquer on it as if it wasnt completely through the clear coat it could have been polished completely out leaving no trace , if it was through the lacquer then a touch up would be needed , sadly you cant polish this out now as the polish and pad would remove all the surrounding lacquer (original) at the same rate and and you will burn through that before you ever got it flat and leave a burn through matt finish where all the lacquer has been removed (then a respray would be needed)2 choices are left now1 , carefully sand the raised area you touched up using a 1500/2000 grade wet sand paper taking care just to remove the lacquer you added and avoid touching the surrounding original lacquer , then once you have it reasonably flush polish the sand marks out leaving a fairly well hidden repair2 , use a paint razor (de-nibber) , this is like a wood plane for paint , it will basically shave off only the raised area of lacquer until flush but again would need a good polisher to then hide the marks left behind there is an alternative to buying a de-nibber which are about £50 which is a old style razor blade (double edged) and holding it flat to the paint slide it back and forth over the area and it will shave off the excess leaving its own damage but that is easily polished out by a machine polisherplease beware you can do serious damage using this method so should be done with extreme care or by a local professionalwith all these options polishing out the leftover marks should really be done by machine polisher as by hand would be a task and a half sorry theres no simple fix , how long ago did you lacquer it , im just thinking if it wasnt through the original lacquer you may still have time to use thinners and remove the lacquer you put on it ?
