I have had two 986 boxsters in the last couple of years and both had headlight seals that sort of turned to a black goo and reminded me of a polyurethane sealant. I searched and searched for replacement gaskets and they only come with new headlights. A few months ago I was in home depot and came up with some Frost King Silicone tear drop profile self stick weatherseal. I stripped the headlights of the old seals and stuck this new weatherseal to the lights and VOILA. I have attached some pictures. I couldn't be happier.:dance:
