I’ve never done those particular cars. As long as a clear coat wasn’t applied over it. Something as simple as Scotch tape may work. Just apply it over the decal. Rub it in a bit and try lifting off.
Solvaset or Micro Sol should also soften it up enough that you can remove it. You can try putting some on a piece of paper towel the size of the decal. The soaked towel just setting on top of the decal for about 10 minutes may be enough to clean it off with a Q Tip or soft brush.
