C2 Coupe weatherstrip installed in which direction

[rbryce1]

I am ready to install the door weatherstrip on my 1965 coupe doors. The doors are off the car and I have the correct weatherstrip with the molded corner section.

I understand the molded corner goes on the rear upper corner and the joint is on the bottom of the door, but there is one question I need the answer to before I start.

An end view of the weatherstrip shows it is not square but shaped like a rectangle. One dimension is longer than the other. One of the longer sides has a slight "groove" in it the length of the strip while the other long side is smooth and straight.



My question is ... which surfaces get glued to the door, the short "flat" and long "flat" surfaces or the short "flat" and long "grooved" surface. Also, and more important, does the rounded surface face the car when the door is shut or does the round surface face the top, bottom, front and rear of the door?

It seems like the round surface would face the car, so when the door is shut, it can compress and seal the door better, but it also the longer dimension as well.

If I get it wrong, the door may not shut or the seal may too short to hold out water.
