As part of my restoration I bought a complete set of Caution and Warning label for my car. Problem I have is they just won't stick in place, especially on the under side of the engine cover ie The Vacuum house routing label. No amount of de greasing or cleaning will let them bond to the surface. What can I do or use to make then stick? I don't want to use a glue that id going to destroy anything.
