Siding needs repair (Wood and Fiberglass)
There you have it. Water damage caused the exterior wall to swell pushing the fiberglass outside the lead extrusion and the wind caught it on our last trip causing it to separate from the wood wit...

I'd do the same as Winged says but not do any leak control until the glass work is done.
FWIW, I sealed up my siding and roof edge trim with Geocel Tripolymer and Eternabond on the roof. All is leak free, now. I believe the standard sealing method for that corner trim is a butyl tape positioned between the siding and the inner corner edge trim. I'd seal up the corner with Tripolymer before putting on the butyl tape, extra insurance. BTW, any rotting wood is not going to get better, it will eventually dissolve into powder.
