A corner in my gutter is leaking because one of the rivets joining two section failed, opening a gap at the bottom of the corner where two sections meet.
I removed the rivet and temporarily put in a screw and nut (screw diameter about 1.5mm) and sealant. I say temporary because the screw is a steel screw. It will rust/rot away.
The original rivet is solid (no hole in middle). I googled for rivet squeezer and it seems like the "C" openings on the rivet tool are not large enough to work on a rivet at the bottom of a gutter.
A pop rivet would work but it would have a hole that water can leak through. What is the correct fastener to use?
