Being a airplane installer, that looks like seal, and because of the coloring of it looks like a window sealer ( silver) and not a door/ panel sealer(black). What doesn't make sense is why it would be on your seat, understanding possibility of it being on the front window. When I picked up mine I did find some black seal dripped on my pillar.See the picture, why where it's so annoying to look at all the time? Seems to be on the seat material as well/
