Potential water leakage at rear lights

[floatingkiwi]

Hi all
Just to let you know that I've found that there seems to be a propensity for leakage at the back lights that I have found on both my families SVX's!!
The right rear light seems to be the worst one: The leak occurs between the light seal and the car body. On both cars I've had to take them off, slightly reform the body to improve the seal surface, and reseal it up with some silicone sealant. The small square plastic plugs below the lights seem to leak very, very slightly as well. Has anyone else found this problem (or a leak in the boot that you can't find?).

Cheers
