White streaks on the windshield

[Uncle Sam]

I have a 2004 Sunvoyager model #8379. I can clean the windshield and then after a little water runs off the roof there will be white streaks on it. It appears that gulfstream did not clear coat the fiberglass cap above the windshield, it appears to be chalking much more than the rest of the coach. I have even though of having this area clearcoated. Another option is to install a gutter across the top of the windshield so the water will run off the ends of it instead of over the glass. But wondering if this will make a noise when driving. Have any of the rest of you had this problem and what have you done to cure it. Also notice that the caulking above the windshield needs to be replaced, what type of caulking should I use?
