Car covers?

[GetCarter]

I'm stuck somewhere for a while with no roof for the 996 tt - need a car cover that will:

1/ keep the bloody bird poo off (and that's LOTS of bird poo).
2/ not wreck the paintwork in strong winds (and that's VERY strong winds).
3/ keep the rain off (and that's BIBLICAL rain).

Your best suggestions welcome.

Thanks in advance.

Steve
