I doubt that penetrating oil will have an effect on any kind of sealer if that is the reason it won't come up. If the penetrating oil won't loosten it up you might try a small amount of acetone. I want to emphasize "small". Acetone will disolve any plastic & most rubber parts it comes into contact with. Acetone will also bugger up the paint so if you have a good paint job you probably want to forget I even mentioned it. grin
