These things cost £8 from Renault and you fit them yourself, probably not worth a group buy. If fitting properly, Renault charge around £100. Might seem a lot but when you've fitted it...you'll soon realise why.
All the sticky crud left by your old seals is hard to fully remove without removing your rear window which is the way Renault do it. I used an array of thin tools wrapped up to stop scratching the car to scrape it away...took a while as its hard to get at.
Best part is the new seals falling off already after under a month! So tempted to glue the damn things, the adhestive is utterly sh*t!!!
Youve been warned!
