Artichoke.
For most of us (though I can't speak for Aero owners) it is a case of minimising the leaks, rather than getting rid of them.
I would have hoped that an Aero Supersport (my dream Mog) would be "drier" than a Trad and would therefore hope that a bit of fettling by your dealer or the factory would improve the situation.
On a Trad, the black art of minimising leaks almost warrants an entire website of its own; but ultimately, most of the Mog owners that I know carry a towel in the car!
Good luck
