I bought a Tyvek car cover a few days ago (custom fit). I am curious, should i leave the windows cracked open before covering the car? Its going to get pretty hot out...id say 90+ degrees. Should i just leave them closed?

I often leave my sunroof open and the windows open a crack just for ventilation.

Does the car cover breathe? if not, there wont be much of a point anyway. I would just leave them closed. I dont think it'll get THAT hot in there, at least less hot than the interior would get with th sun baking right on it. What color is the cover?

Tyvek isn't going to breathe especially if it was custom fitted. That is one reason it is used as house wrap.

So, I'd say any argument about letting hot air out of the car is mitigated and keep the windows closed so bugs don't get inside. If the cover is white or light shade shouldn't get too hot inside the car.

Yup, color is white. Ill just leave it closed then. Thanks guys.
