Problem is the movement which is why gutters have rubber gasket.

I'd try gutter sealant. Polymer based...

I've used gutter sealant and it's ok for a few years, then it hardens and becomes brittle.
Lead sealant is my favourite, after 18 years in my house the gutters and downpipes are still leak free.
