I just discovered the source of huge amounts of water getting into the trunk and then into the back seat was a severely worn/rotted tail light gasket. No auto parts stores in my area carry them. I also called a couple import shops in the area and they don't have them either. I called several honda dealerships as well, none of them carry the gaskets and they all told me the same story - they would have to order them and there are only TWO left in the entire US! Wow.

Does anyone know where I might find some? After market brands would be fine. In the meantime I've made one to at least get me by for a while.
