I took the rear side panel and roof lining of and checked the joint and it was fine , I even took it apart and tried the washer and water shot 6 foot across the garage so I know water is getting that far so I got a replacement nozzels and am trying to get the top cowling off to replace them but am struggling. I have removed the five nuts holding it on and released two clips either end but it seems that there are a couple more near the centre by the brake light and I don't want to force it incase the cowling creases or worse snaps so any ideas to remove greatly recieved.
