Rejuvenate an L400 front sunroof seal
Posted: Thu Aug 02, 2012 8:33 am
With thanks to Drumster, I believe I have fixed my leaky front sunroof. Thought I would share it for any others who might have an old gasket.
I have taken two approaches to fixing the leak. Previously, I took the overly cavalier approach and siliconed the whole thing shut. Worked great but has clear implications for functionality.
The second road taken was to revive the gasket a bit with some detailing product. Then stuff a piece of cotton string under the gasket. The string flares up the gasket enough to seal but not so much it causes problems.
So far it's working very well.
Lesson learned for me: only silicone things closed when you are confident that you will never ever ever ever open tem again. Silicone removal is a wretched task.
