A quick question about POR15 and drip rail.

POR 15 is great stuff but there is a better and cheaper way. If the caulking is coming off you will want to replace it all. There is a pinch weld there and caulking is a must. You will need to take out all the old caulking. Once you do this, mask off the driprail molding and also run some tape on the roof close to the edge of the old caulking. You may want to double up on the tape. Use a piece of sandpaper or scotch brite pad in the gutter to remove any old caulking or any surface rust. make sure the gutter is clean. Use a wax and greese remover to remove any contaminants. Once the gutter is clean, use a good quality 2k direct to metal primer or epoxy. You can apply it with a small brush. It will need to dry for about 12 hrs. At this point you will want to re mask the driprail molding and roof. You should also put a peice of tape over both ends of the driprail so nothing can drip out. Next use a brush to put on a good quality seam sealer, you will want to put on 2-3 coats. wait until each coat drys before you put on the next coat. You can paint over most seam sealers so no need to use a primer to top coat. Try to get the last coat of seam sealer on as smooth as possible. Take your time and don't rush in between each step...Hope this helps.
