If this is a clamp of flush window? The butyl seal on clamp windows csn fail. Before wasting time slathering sealant all over the window, take it out, clean everything throroughly, go buy a roll of butyl putty tape. Apply all around the window, reinstal. Clean excess squeeze out, now, apply a small bead of Dicor around the top and sides of the window. Now you have a professional, permanent fix.
exactly. don't do a band aid by putting something around the outside. First find out why it leaked, correct it and install properly which will in almost all cases mean some kind of butyl tape, then and only then use a caulk around the outside.
