Thanks for everyone's input. I really think the silicone sealant will take care of it. Also welcome to Hawkske. You are correct, there is a lot of support here. A great group of people. I think you will be happy with your Crossfire.....Congrats.

 

Thanks for the info. I found a list of common problems. I have been reading older posts and have learned alot already. So glad I found this site. Seems like a great group of people helping each other out. I have been having a blast driving mine!

 

Final report. Used a black silicone adhesive. Put down a thin bead along tiny gap between rubber seal and top edge of windshield frame. Smoothed out with fingertip. Black car, black rubber and black silicone......impossible to see.....all blends. Let it set up for a day then a test drive.......no more whistle!! Problem solved. We had put up with it for the 3.5 months that we have owned, but the prior owner had listened to it for 8 years!!!
