The new product that replaces the old metal top channel,
Does it secure with small screws or just glue?
When shaping it to fit the door frame it really wants to kink or buckle when making the 90 degree bend at the rear of the door, any tricks?
It does tend to kink, but once you get it into place, you can get the kinks out with a big screw driver. The congregations in the metal makes this possible. I use tiny screws where ever they are needed.
