If it's dried lumps rater than a smear, maybe trying some Meguiars Clay, I used it to get spots of house paint off of my car (it involves a lot of scrubbing and elbow grease but doesn't damage the paint).
However, may not work if the super glue isn't raised at all and it's abouut £20 for the kit so although it's an idea, might be best trying something cheaper first! Saying that, it's good stuff for getting tar and other road rubbish off anyway.
