Anybody know how to correct the following. A magnetic decal was left on a car for about a week. When it was removed it left the paint with a cloudy/foggy mark. I have the following products Menzerna Super finish, Menzerna Power finish, Menzerna Power gloss, and M105 with Uber pads ranging from cut down to glaze. I've tried Menzerna Power finish with a medium pad without success. I'm not sure if the mark is permanent or not?
