Its supposed to be some special super sticky swishy sealed wet glass mat affair that goes with the (in)efficient dynamic system - the system that is supposed to save you fuel by only charging the battery on overrun but actually costs you fuel because you have to do extra miles every trip to keep the sodding battery charged up!
