Hi Joe,
On my current car and as best that I can recall from my Triumph youth,
the sill under the chrome strip was black undercoating. If I'm right it
was used to resist stone & debris chips. When I refreshed the sills on
my car I used 3M brand spray undercoat. This product had a low sheen
appearance & is very durable. It goes on lighter than the inexpensive on
the shelf products. I was only able to get it from auto body supply houses.
The black line continues straight parallel to the underside of the
chrome strip to the edge & wraps around the return on the front & rear
fenders.
