I also have this cover, great from summer but in this weather I get the same but not the inside the windscreen issue.......
ive only had mine since the summer, and already the inner material is flaking off and again, taking the cover off not only do I have light condensation on the car and get white bits over the car (and no it's not me getting excited that I'm just about to get in and drive it) lol lucky the car is waxed up and with a quick wipe and then quick detailer as she warms up it hasn't caused any problems for me, but I will be replacing this cover ASAP
