I find that my car cover leaves a "film" on the car, especially the windshield.
We are going to be away for a month, I was thinking to give the car a good wash and dry then drape it with a thin plastic drop cloth and then the car cover, it is in the garage...so what cha' think?

Indoor or outdoor? If you're parking the car and you're going to be gone, there isn't really any reason to cover it in your garage. The main reason I cover my car in the garage is to avoid human related accidents (i.e. KIDS!).

I have an outdoor cover too, but I've never used that one. If anyone wants an OEM 997 997.2 outdoor cover send me a PM. I paid $300 for it.

Live with the film (maybe the cover needs a cleaning) and clean the car when you get home. I highly recommend you DO NOT place a plastic film of any type on the car for an extended period of time. The cover needs to breath or it will trap moisture.

As said above your cover leaves a film because it is dirty and needs a wash. I don't recommend leaving the car covered outside since after a rain the moisture will not scape easily and may leave a haze on the paint. If you are storing it indoors with the cover, allow the car to dry completely before covering it.

What I do for Winter storage is clean and wash the car, but leave to dry out properly, park in garage / storage put cover on , I also drape a tarp over the cover incase any roof leaks happen in storage.
I'd leave the plastic sheet alone

I don't know what to do, I know that the cover is clean, it's brand new only used inside the garage.
Many years ago I bought a used 77 Carrera ((long story, I bought a Carrera from Kremer in Koln Germany, they took me on a tour of their facility and in the basement they had about 10 of their retired race cars all covered with only thin plastic sheet...they said that is how them keep them dust free....so what could happen if the car is dry, stored in the garage ??

the residue under the cover is from condensation and powder formed by an aging cover. evolution cover breaks down after a few years leaving a powder residue.

you are leaving the car for a month, hardly long term at all. i wouldn't bother with pulling a plastic covering under the cover.

i would put a battery tender on the car though.

Cabriolet owners have a bit of a dilemma. The better cover will not shed lint on your top so it needs to be something other than cotton. If so, it will be more weatherproof. The weatherproof covers will possibly leave a 'film' when you remove the cover. The best bet is to only cover the car when it is completely clean, and to launder the cover as needed.

The OP says his cover is clean and new, so a dirty cover doesn't seem like the problem. especially if what he is seeing is a film and not dust. I think some of the breathable covers are treated chemically to make them semi water repellant. I wonder if outgassing of the chemicals could be causing the film in the same way that a vinyl dash will outgas a film onto the inside of a windshield?
