I have just had an interesting chat with James Geddes who has shed some light on this real seal matter. Apparently Belgian manufactured vehicles had a rubber seal all others were used some sort of sealant. Not really sure how the club ended up with these in stock then. At some point when the weather is warmer I am going to take my rear screen out and try this rubber seal. If not suitable will use a black sealant as the current one is clear and looks a bit ‘ naff ‘.
