I did nothing to my top and the water just beads right up on the surface. I towel dry the beads and the top is bone dry. That may be because the car has never been caught in the rain and the top has only been wet when washed which hasn't been too often as its in a garage every night and when taken to work its under a cover during the day. When its out the top is down or its not nice enough for it to be out.
