For a long time, my gutter trim kept peeling back from the front corner
by the windshield. I figured to replace it but I didn't like all the
trims that I looked at as replacement trims. Most had a separate end
piece that had to be held with a screw. That didn't sit well.
What to do?

Solution.

I pulled the trim back a bit, then cleaned the groove in the trim with a
scraping tool, and then cleaned the metal strip the trim mounts on very
thoroughly with MEK. Al old tar/glue was removed. The I squirted
"Plumber's GOOP" into the trim groove, and shoved it down tight onto the
metal trim mount. That trim strip has not moved since.

Plumber's GOOP works.
