Hole in skylight over shower

[Wildflower]

Have a 2013 Ambassador that has been the "coach from hell". Just picked it up from the dealer after it took six weeks to complete all the repairs from issues we found on it's first trip. This morning we found water coming in from around the shower skylight. After taking the inner liner out we found a small hole/crack that appears as though when they were repairing a roof issue perhaps some dropped a tool or something on it. At any rate, we are settled in and hooked up at our summer location and prefer not to pull up stakes and drive the 150 miles back to the dealer for repair. Any suggestions on how to seal that hole until the unit ones back in the fall? We're leaving the liner out so thi gs can dry out but obviously the hole needs repaired. Thanks.

Take pictures of it, and call the dealer so you are on record with them. This might help so that they won't hassle you in a couple of months when you take it it.
