Rain Gutter Sealing
You need to remove anything that is remotely close to loose. Then you can replace with seam sealer.
Honestly I would remove it all and start from scratch. You would be surprised how much rust can be hiding under that seam sealer.
I just stripped the drip edge on a friends 67 barracuda yesterday. It looked fine other than some places it was separating. One side was rusted the whole way down. Not bad rust but it would have been if left.
Here is a picture of it cleaned and epoxy primed after. I didnt get a before pic unfortunately.
