Just enquiring to see if anyone has removed and blanked off the rear washer jet nozzle from the roof on a 4th gen.
The one on my car was leaking so i had a few goes fixing it - its now a bit of a mess and have already removed the rear wiper and motor so its no longer needed.
I am looking for any suggestions on how and what to blank it off with and any tips on removing the washer jet itself without damaging the roof - its difficult to get at and it does not seem to want to budge and the roof flexes as its weak there.

Finally got the leaky washer jet off and replaced it with one of these evo style shark fin diffusers. It covers the hole from the washer jet perfectly and doesnt look out of place imo. Ive also removed the rear wiper motor and fitted a nice gloss black bung that i got off ebay for a couple of quid.
Can get a pic if anyone else is thinking of doing the same and ive got 7 or 8 of the shark fins left spare
