I have always had a small squeege in the trunk - and every morning i give it a couple of drags across the rag top - stops it draining into the car when i open the door - and also that nasty vacuumm suck should i put the top down wet.
Jst one of them rag top things!! Like always having a spare baseball cap (preferably clean) in the car so should you offer someone a lift they can keep their hair together - nothing ruins a first date more than messed up hair - for some people.
