Crazy question... I do know that these comments are from back in 2014 but MSGulfCoast or anyone actually... what do you all think about (Don't Laugh too hard) a light coating of the Flex Seal Spray and then some insulation either fiberglass or the foam sheeting? I have an 02 Fleetwood Discovery that has the same issue with little to no insulation up behind the "entertainment center". Not only that I have been chasing a water leak up there too, and yes there is some wind noise up there as well. I don't have to worry about the clearance lights or windshield wiper motors.
Anyway any thoughts on using the Flex Seal stuff??
Thanks All!! :-)
