What can I seal crooked screw heads with?
While investigating a leak today, I found that several of the screws under the rubber 'strip' that is part of the rain gutter were installed crooked, leaving gaps between one side of the screw head and the hole behind it. Any water that gets to the space between the rubber strip and the screw/rail can (and has, sadly) cause a leak.There's butyl tape between the exterior siding and the back of the gutter rail, but no seal on the screws themselves.
I'm not sure the rubber is supposed to keep water out of that area - but its not.
I want to put some kind of sealant over the screw heads to ensure that water can't get past them.
What kind of sealant can I use here, knowing it can't be too bulky or the rubber strip won't seat in place over it...
