Lacquer thinner on a Q tip. If you are very careful and only use a little at a time you should be able to get it off. Just dab in on the tag and wipe it off. You will have to experiment with each tag but you will get good after a short while. When you get most of it off you can try using rubbing compound and then polishing compound for the last little bit. Take a few of your old parts to the places where you bought your parts from and have them tag them and then practice on those pieces. If you screw up you can always repaint the whole thing. Good luck.
