Interior rain seal question

About the sealant...
There is some stuff used in later models thats great. I discovered it in late 80s Honda. Its a beige color similar litium grease. It has a string in it so it may come on a roll. I'll hunt down a source for it myself when the "need it" time comes. It is afterall a moisture bearier to save the interior door panels .
Remember to cut the plastic long enough to reach into the slot at bottom of door like factory did or the water will run down the inside of painted kick plate area.
