Bentley GTC Third brake light, water leak

Hi , I'm new to this Forum and hoping someone out there will be able to shed some light on an issue I'm facing with my 08 Bentley GTC.
i have leak where water is finding its way into the car and boot, after some research I've been informed that its a common problem and because of thin perished seals around the 3rd brake light water leaks into the car.!
has anyone else experienced this?
I've heard there is a modification using thicker seals which can be fitted.
does anyone know how to remove the light?

I found this in another thread-hope it helps:

The changing of the 3rd brake light is not difficult. It is caused by moisture that comes in from a bad seal...

Use the roof up button....and stop the apron when it is standing up

Under the apron there is a felt skirt that needs to come off. Gently remove the snap buttons and don't break them, you will need to reuse them. Once you take off the skirt you will than be able to remove the 3rd brake light. It has hex screws and nuts that need to loosen and remove.

Note: you will notice that the felt skirt will feel moist, which is an indication that water is getting in and the culprit behind the light not working.

Once all of the screws and nuts are out you can gentle remove the light. There is also sealent tape that might be needed to be replaced.
