If you put a tarp under the cover moisture will still get underneath. Since it will not be able to breath the paint fill fade. No car cover is completely waterproof nor should it for it to breath.
I'm in New England and I bought a Seal Skin for my old Porsche. Garbage. The first leaked. The car was completely wet underneath. So, I reported it to them and for $35 they'd send me another. I did. It stayed waterproof for about two weeks. I have to put a tarp underneath now. The Seal Skin is a little better looking than a tarp so I double them up. Don't fall for the paid endorsers or the hype. They suck.
