This is quite the collection of excellent experience and advice.
There is a wealth of info here at my fingertips.
I discovered iRV2 as I was looking for help with a problem:
it keeps popping out of the gasket (and whistling like a locomotive) or cracking the glass when sealant is used to fix the popped out area. 2000 National RV Tradewinds, 2 piece windshield with figure 8 gasket, center locking bead on gasket.
Its been a recurring problem for 6 years now.
Sound familiar to anybody?
I think I should start a thread over in another section, like problems and fixes?
