Occasionally water will show up on the entertainment counter under rear window.There is a perforated rubber in the tract which always has water under it during rain events.Is this normal? This is the only window that is leaking but a couple others have water under the rubber tract. Upon inspection of the window outside , it is not tight against the fiberglass. Probably about a 1/4 " gap in center on left side for approx a foot. Would I be advised to caulk down the sides?...Any opinions on this?
