What kind of sealer to to get?

Well, I took apart my stock headlight (again) due to the condensation problem I was having. It looked as though the seal that I used before (liquid nails) was perhaps NOT the best choice afterall. The gray-colored sealer that Honda uses... is it available anywhere? Does anyone know what it is called? Anyone out there know what would be good to use to keep moisture out? I appreciate any help! Thanks! Cyber

you can try the dealership. otherwise use some of the clear silicon sealer and just go crazy with the stuff.
